To guarantee the ecologic function supply in central China, such as biodiversity and water conservation, the ecological spatial pattern in the Qinba Mountain Area should be optimized; specifically, the spatial system of protected areas centering on national parks need to be improved and implemented. This study spatially identifies the main ecological corridors in the Qinba Mountain Area by analyzing suitable habitat conditions of indicator species and using minimum cost path calculation, and then clarifies the protection gaps according to the distribution of existing protected areas. It is suggested that a Funiu Mountain National Park should be built in this area and a Qinling National Park should be established covering the Shaanxi Province area of the existing Panda National Park. By this means, the spatial layout of four National Parks is formed in this area. On this basis, natural parks of other types can be newly built to further improve the existing gaps in the protection of important rare species and water sources.

This study aims to solve some practical problems existing in the Qinba Mountain Area including the scattered spatial distribution of rural residents, its prominent contradiction with the nature reserves, the outflow of rural population, the weak industrial economy, and the loss of environmental characteristics. Based on the idea of constructing a reserved natural area system centering on national parks, the development path of rural revitalization and differentiated development modes are proposed, which accord with regional features and coordinate protection with development. A rural revitalization strategy suitable for the Qinba Mountain Area is also actively explored through specific measures, including adjustment of rural residential space, development of rural green industry,construction of rural characteristic landscape, and improvement of rural service system. The research results reveal that coordinated and sustainable development of ecological protection, cultural heritage, and rural revitalization can be realized in the Qinba Mountain Area by effectively coordinating the development relationship between villages and nature reserves.

Community-based co-management (CBCM) is considered as an effective approach to coordinate the relations between ecological conservation and sustainable development. This study aims to provide suggestions for optimizing the CBCM system of protected areas in the Qinba Mountain Area by analyzing the coordinated paths, successful experiences, and current issues of typical CBCM cases. By literature review, field investigation, expert interviews, and comparative case studies, we thoroughly analyzed five typical CBCM cases in protected areas in the Qinba Mountain Area, namely Jiuzhaigou, Tangjiahe, Zhuhuan, Taibaishan, and Baishuijiang Nature Reserves. We also summarized 12 coordination approaches of CBCM from the perspectives of government, market, and society; and found 4 successful experiences (leading by government, adopting multiple approaches, reflecting regional characteristics, and making mechanism innovation) as well as 4 major issues (i.e., incomplete eco-industry, low capability of communities, unrecognized eco-cultures, and insufficient state support). At the theoretical level, we analyzed CBCM from three dimensions, namely equity vs. efficiency, centralization vs. decentralization, and public benefits vs. private interests. And at the practical level, we provided policy recommendations at national, regional, and protected area levels.

Seeking water and earning their livelihoods is the natural selection of human beings. Like other rivers on the earth, the Yangtze River is the birthplace of human civilization and survival. As an ecosystem, the Yangtze River Basin is evolving under the influences of natural factors and human activities. Because of soil erosion, pollution and human activities, the imbalance of secondary environment is exacerbated and the ecological environment has become more vulnerable. It is urgent to mitigate and prevent the ecological crisis. The practice has proved that implementation of engineering measures is an effective way to improve the ecological environment. The Three Gorges Project (TGP) has a flood control storage capacity of 22.15 billion m3, effectively storing the flood water upstream of Yichang, and protects 15 million people and 1.5 million hm2 farmland. Furthermore, the project can prevent or slow down the sedimentation and shrinkage of the lakes in the middle Yangtze River such as Dongting Lake; with an average annual power generation of about 90 billion kW·h, it can significantly reduce CO2 and harmful gas emission. In general, the construction of TGP is conducive to the ecological and environmental protection in the Yangtze River Basin and China, even the world.

In the National "11th Five-year" period,the Liaohe River basin water pollution control acquired breakthrough progress. It eliminated water quality worse than class V for chemical oxygen demand (COD) in the mainstream of the whole river basin. In order to consolidate the control achievements of the Liaohe River mainstream,and to achieve long-term goal of sustainable development,Liaoning Provincial Government desi-gnated the mainstream of Liaohe as conservation area and established a conservation bureau. This is the first administration to be set up in China carrying out integrated basin management. So we do the research about the Liaohe River control and conservation. The goal of the research was to restore a healthy river ecosystem including flood control,good water quality,healthy ecology and beautiful landscape. It's realize the integration of hydraulics,ecology,environmentology,landscape esthetics,economics and other interdisciplinary concept in ecological environment protection plan of China.

In recent years, a series of ecological protection and restoration projects has been implemented in North China, and the vegetation conditions have changed significantly. Exploring the impact of regional vegetation restoration on the water circulation process and the balance of water supply and demand is important for improving ecological restoration strategies and realizing the sustainable utilization of regional water resources. This study conducted a comprehensive analysis using the Pearson correlation coefficient and Moran’s I index and based on multi-source water covariate data. The spatial and temporal variation of vegetation and different water covariates is analyzed, the water resource effects of vegetation conservation and restoration are identified, and the tradeoff between water resources and vegetation restoration is discussed. The results show that the effects of ecological protection and restoration projects are remarkable, with the net primary productivity increasing at a rate of approximately 2.3 times faster than that outside the project area; the vegetation expansion and evapotranspiration show strong spatial and temporal correlations; and the increase in evapotranspiration owing to vegetation restoration is the main reason for the deficit or significant reduction in water storage. Therefore, it is necessary to improve the implementation strategy of ecological restoration while considering the restriction of water resources on vegetation conservation and restoration, strengthen the dominant position of the ecosystem’s own resilience, and promote the sustainability of vegetation restoration and the sustainable use of regional water esources.

Fastigial Nucleus Electrical Stimulation and Central Neurogenic Neuroprotection

Strategic Study of CAE 2001, Volume 3, Issue 11, Pages 32-38
Brian can protect itself from ischemia and/or hypoxia by two distinct mechanisms which probably involve two separate systems of neurons in the CNS. The first ome mediates a reflex neurogenic neuroprotection, which is associated with oxygen-sensitive sympathoexcitatory reticulospinal neurons of rostral ventrolateral medula oblongata. It can be excited within seconds by reduction in blood flow or oxygen and initiate an oxygen conserving reflex. The second is conditioned central neurogenic neuroprotection, which is represented in intrinsic neurons in cerebellar fastigial nucleus. It can be initiated by electrical excitation of intrinsic neurons of fastigial nucleus and afford a persisting for almost two weeks neuroprotection. This mode of neuroprotection is not restricted to focal ischmia,it also protects the brain against global ischemia and excitotoxic cell injury. The ne-oruprotective mechanism of the system is associated with reduced excitability of cortical neurons, inhibition of the onset of necrosis and apoptosis of ischemic neurons, reduced expression of many detrimental factors including Caspase-3 and NF-kappaB, and reduced immunoreactivity of cerebral microvessels. Fastigial neucleus stimulation can also promote the recovery of neurological deficits and can somewhat improve the cognitive function. Some prelimilary observations of clinical application of fastigial nucleus electrical stimulation on protecting neurons from ischemic injury and treating patients with stroke are presented. Recommendations of further research on fastigial nucleus stimulation before its broad clinical practice are provided.

Variational principles of smoke temperature are studied in confined space with water mist applying. Effect of ventilation area, position between ventilation and fire and water mist flux on temperature decreasing velocity is studied by experiments. The attenuation of temperature decreasing velocity is described under different ventilation conditions. It is found in experiments that the attenuation of temperature decreasing velocity caused by ventilation can be reduced by increasing water mist flux. This paper provides necessary references for water mist application in fire protection.

Strategic Study of CAE 2015, Volume 17, Issue 6, Pages 65-69
Spontaneous abortion is a complication of pregnancy that terminates before 28 weeks of gestations. The incidence is about 15 % ~ 40 %. In recent years the assisted reproductive technology(ART) is also facing the problem of high incidence of spontaneous abortion. Etiology of spontaneous abortion is very complex. Besides genetic factors,there are anatomical factors,endocrinological factors,infection factors,environmental factors,immunological factors,prethrombotic state and maternal systemic diseases and so on. Cytogenetic studies of spontaneous abortion are mainly in two aspects,one is embryonic chromosomal abnormalities,including the number of chromosome abnormalities and abnormal structure；the second is couple of chromosome abnormalities. In spontaneous abortion the embryonic chromosomal abnormal detection rate is around 60 % and this ratio declines with the increase in the number of abortions. Most of the number of embryos abnormalities are trisomy,triploids and X monomer. Less structural chromosomal abnormalities of embryo include chromosomal breakage,inversions,deletions and translocations and so on. In couples with spontaneous abortion,especially recurrent spontaneous abortion couples,the abnormal chromosome detection rate is around 8 %. With the number of abortion increases,this proportion increases too. The most common abnormality of chromosome of adult is balanced translocation. Nowadays there are great developments in cytogenetic detection technology. From the traditional chromosome karyotype analysis and fluorescence in situ hybridization techniques (FISH) to chromosomal microarray chip analysis and the second generation sequencing technology,we can make further research of cytogenetic of spontaneous abortion. These researches have a very important significance in the area of etiology of spontaneous abortion and do great help to guide the couples confused by recurrent spontaneous abortion in their next childbirth.
