Integrated benefits of power generation by straw biomass —A case study on the Sheyang Straw Power Plants

Xiaoshun LI , Futian QU , Dongmei JIANG , Peixin ZHU ,

《环境科学与工程前沿（英文）》 2009年 第3卷 第3期   页码 348-353 doi: 10.1007/s11783-009-0026-3

摘要： Power generation using straw biomass has quantifiable benefits from an economic, ecological, and sociological perspective in China. The methods used to construct the assessment models of these integrated benefits were the revenue capitalization approach and the discounted-cash-flow approach. The results indicated that a straw power plant with the capacity of 2.50×10 W and burning 1.23×10 tons of cotton straw could annually supply 1.40×10 kWh of power. However, it would not be until six years later that these results could be measured. Over the long term, the gross benefits could reach up to 4.63×10 Yuan. Therefore, the total benefits are expected to be 1.18 × 10 Yuan if all available straw resources are used to generate power. The policy implication showed that the long-term integrated benefits of power generation by straw biomass outweighed the short-term benefits. This is the main incentive to use straw biomass for power generation in the future.

摘要： A number of ethnic minorities are being distributed in southwest China. Yunnan Province is an area inhabited by multi-ethnic groups. For a long time, the ethnic groups have been interacted by others in the cultural aspect, while retaining their own ethnic traditions. The performances of ethnic groups’ dwelling houses are similar as determined by natural and cultural elements of the same area. This paper mainly analyzes decisive factors behind similar appearances by the way of field research on two minorities, Nu ethnic group and Li-su ethnic group, in the Fugong county, Nujiang Li-su autonomous prefecture. Moreover, the paper tries to summarize the commonality and individuality of the minorities in order to provide useful theoretical reference for the minorities building of new socialist countryside in the future.

Ecosystem service tradeoff between traditional and modern agriculture: a case study in Congjiang County

Dan ZHANG, Qingwen MIN, Moucheng LIU, Shengkui CHENG

《环境科学与工程前沿（英文）》 2012年 第6卷 第5期   页码 743-752 doi: 10.1007/s11783-011-0385-4

摘要： Besides crops, agriculture supplies all three major categories of ecosystem services (ES). However, agriculture also supplies an array of ecosystem dis-services (EDS) that may harm other ecosystems. The flows of ES and EDS are directly dependent on the management of agricultural ecosystems. The traditional method of Chinese agriculture, which supports sustainable agriculture, has been proven to increase ES and reduce EDS. However, there is a lack of a detailed understanding of the ES and EDS associated with traditional agriculture, and also of differences between traditional and modern agriculture. In this study, an investigation was conducted on the ecosystem services (ES) and ecosystem dis-services (EDS) of traditional and modern agriculture in Congjiang County, Guizhou Province, China. Afterwards, the economic values of ES and EDS were quantified experimentally and calculated based on the market price. The results show that: the net economic value of traditional rice-fish agriculture was 3.31×10 CNY·ha (6.83 CNY= 1 USD as of July, 2009) and that of rice monoculture was 1.99×10 CNY·ha . Significant differences existed between traditional rice-fish and rice monoculture fields for their economic values of some ES or EDS. A benefit and cost analysis (BCA) model was used to adjust the conflict between the economic income and environmental loss from traditional and modern agriculture. The BCA model not only calculates the net income but also monetizes the EDS of the agricultural systems. The results showed that the net income of rice-fish agriculture was 1.94×10 CNY·ha higher than that of rice monoculture. However, the benefit to cost ratio (BCR) of rice-fish agriculture was lower than that of rice monoculture, indicating that the traditional agricultural model was not the most optimized choice for farmers. The value of the rice-fish agriculture was much higher than that of the rice monoculture. Thus, when considering the benefits that rice-fish agriculture contributes to the large-scale society, these agricultural methods needs to be utilized. Furthermore, the labor opportunity costs were calculated and the comprehensive value of rice monoculture was negative. Finally, the compensation standard was calculated based on the comprehensive benefit analysis. The lowest level was 1.09×10 CNY·ha , and the highest level was 1.21×10 CNY·ha .

Cluster voltage control method for “Whole County” distributed photovoltaics based on improved differential

《能源前沿（英文）》   页码 782-795 doi: 10.1007/s11708-023-0905-8

摘要： China is vigorously promoting the “whole county promotion” of distributed photovoltaics (DPVs). However, the high penetration rate of DPVs has brought problems such as voltage violation and power quality degradation to the distribution network, seriously affecting the safety and reliability of the power system. The traditional centralized control method of the distribution network has the problem of low efficiency, which is not practical enough in engineering practice. To address the problems, this paper proposes a cluster voltage control method for distributed photovoltaic grid-connected distribution network. First, it partitions the distribution network into clusters, and different clusters exchange terminal voltage information through a “virtual slack bus.” Then, in each cluster, based on the control strategy of “reactive power compensation first, active power curtailment later,” it employs an improved differential evolution (IDE) algorithm based on Cauchy disturbance to control the voltage. Simulation results in two different distribution systems show that the proposed method not only greatly improves the operational efficiency of the algorithm but also effectively controls the voltage of the distribution network, and maximizes the consumption capacity of DPVs based on qualified voltage.

spectral characterization of soil dissolved organic matters in the fluctuating water-level zone of Kai County

Fang FANG, Yan YANG, Jinsong GUO, Hong ZHOU, Chuan FU, Zhe LI

《环境科学与工程前沿（英文）》 2011年 第5卷 第3期   页码 426-434 doi: 10.1007/s11783-010-0264-4

摘要： Three-dimensional fluorescence spectroscopy was used to investigate the fluorescent properties of soil dissolved organic matter (DOM) in the water-level-fluctuation zone (WLFZ) of Kai County, Three Gorges Reservoir (TGR). Most of the soil DOM analyzed in this study was found to contain four fluorescence peaks. Peaks A and C represent humic-like fluorescence, whereas peaks B and D represent tryptophan-like fluorescence. Peaks E and F, which represent tyrosine-like fluorescence, only appeared in certain soils. Soil humus was the main source of DOM in soil, and higher concentration of soil DOM was found in the exposed soil than submerged soil. Compared to the peaks A and B, the fluorescence intensities of peaks C and D were strongly influenced by the fluctuating water level. Analysis of fluorescence intensities of different peaks in soil DOM showed that WLFZ soil was not contaminated significantly. Soil DOM contained at least two types of humic-like fluorescence groups and two types of protein-like fluorescence groups. The proportion of the content of peak A in soil organic matter was quite stable. The soil DOM in exposed soil had relatively high humification and aromaticity, and periodic submerging and exposure of soil had an impact on the humification of soil DOM.

摘要：

Following its 40-year reform and ‘Open Door’ policy, China has recently proposed a new approach to green development and rural revitalization—the idea of Agriculture Green Development (AGD), with the key feature of creating a green eco-environment. In this mini-review we introduce the definition, theory, framework and major components of a green eco-environment as a key part of the AGD. We define a green eco-environment as including four key elements or measures: (1) a green eco-environmental indicator system; (2) environmental monitoring and warning networks; (3) emission standards and environmental thresholds for key pollutants; (4) emission controls and pollution remediation technologies. We have used Quzhou County (a typical county in the center of the North China Plain) as an example to show how detailed air, water and soil monitoring networks, as well as improved farmer practices and pollution control measures (especially ammonia emission mitigation and PM pollution reduction), can begin to create a green eco-environment in China and that AGD is possible. We conclude by stressing the need to improve the framework and practice for a green eco-environment, especially the importance of linking proposals and practices for a green eco-environment with the United Nations high priority Sustainable Development Goals.
