我国人多地少,随着经济建设的迅速发展,各种基本建设占用大量耕地。人口增加和耕地减少的矛盾日益突出。为了保证经济建设的可持续发展,我国政府决定实施基本农田保护制度,在详查耕地面积的基础上,划分出1,2级优质耕地作为基本农田强制保护。基本农田保护制度是中国可持续发展的重要保证,将永葆中华民族的繁荣昌盛。

Various process-based models are extensively being used to analyze and forecast catchment hydrology and water quality. However, it is always important to select the appropriate hydrological and water quality modeling tools to predict and analyze the watershed and also consider their strengths and weaknesses. Different factors such as data availability, hydrological, hydraulic, and water quality processes and their desired level of complexity are crucial for selecting a plausible modeling tool. This review is focused on suitable model selection with a focus on desired hydrological, hydraulic and water quality processes (nitrogen fate and transport in surface, subsurface and groundwater bodies) by keeping in view the typical lowland catchments with intensive agricultural land use, higher groundwater tables, and decreased retention times due to the provision of artificial drainage. In this study, four different physically based, partially and fully distributed integrated water modeling tools, SWAT (soil and water assessment tool), SWIM (soil and water integrated model), HSPF (hydrological simulation program– FORTRAN) and a combination of tools from DHI (MIKE SHE coupled with MIKE 11 and ECO Lab), have been reviewed particularly for the Tollense River catchment located in North-eastern Germany. DHI combined tools and SWAT were more suitable for simulating the desired hydrological processes, but in the case of river hydraulics and water quality, the DHI family of tools has an edge due to their integrated coupling between MIKE SHE, MIKE 11 and ECO Lab. In case of SWAT, it needs to be coupled with another tool to model the hydraulics in the Tollense River as SWAT does not include backwater effects and provision of control structures. However, both SWAT and DHI tools are more data demanding in comparison to SWIM and HSPF. For studying nitrogen fate and transport in unsaturated, saturated, and river zone, HSPF was a better model to simulate the desired nitrogen transformation and transport processes. However, for nitrogen dynamics and transformations in shallow streams, ECO Lab had an edge due its flexibility for inclusion of user-desired water quality parameters and processes. In the case of SWIM, most of the input data and governing equations are similar to SWAT but it does not include water bodies (ponds and lakes), wetlands and drainage systems. In this review, only the processes that were needed to simulate the Tollense River catchment were considered, however the resulted model selection criteria can be generalized to other lowland catchments in Australia, North-western Europe and North America with similar complexity.

农业资源与生态环境是保障粮食安全的基础,当前,中国农业资源与生态环境主要面临三方面的问题:第一,由于播种面积减少、耕地质量下降和空间格局变化造成我国耕地资源对粮食生产的后续支撑能力不足;第二,“水减粮增”矛盾突出和“北粮南运”难以为继;第三,农业生态环境恶化、农业生态系统服务功能难以充分发挥。为解决这些问题,需要实施现代高效生态农业战略、粮食生产区再平衡战略和贸易替代战略。基于此提出了相应的政策建议。

Assessment of soil health requires complex evaluation of properties and functions responsible for a broad range of ecosystem services. Numerous soil quality indices (SQI) have been suggested for the evaluation of specific groups of soil functions, but comparison of various SQI is impossible because they are based on a combination of specific soil properties. To avoid this problem, we suggest an SQI-area approach based on the comparison of the areas on a radar diagram of a combination of chemical, biological and physical properties. The new approach is independent of the SQI principle and allows rapid and simple comparison of parameter groups and soils. Another approach analyzing the resistance and sensitivity of properties to degradation is suggested for a detailed evaluation of soil health. The resistance and sensitivity of soil properties are determined through comparison with the decrease of soil organic carbon (SOC) as a universal parameter responsible for many functions. The SQI-area and resistance/sensitivity approaches were tested based on the recovery of Phaeozems and Chernozems chronosequences after the abandonment of agricultural soils. Both the SQI-area and the resistance/sensitivity approaches are useful for basic and applied research, and for decision-makers to evaluate land-use practices and measure the degree of soil degradation.

海陆关联工程是指在建设和运行中同时涉及陆域和海域并发挥显著作用或产生重大影响的工程项目,主要包括港口、跨海桥梁、海底隧道、填海工程等。近年来,我国海陆关联工程的建设快速发展,工程技术的总体水平得到了提高,在沿海经济发展中发挥了显著的作用,但也存在发展不平衡、协调性较差、环境和安全管理相对薄弱等问题。未来我国应逐步推进从沿海到深海大洋、从示范试点到全面铺开、从单一工程到复合工程的海陆关联工程体系的建设,重点在沿海产业涉海工程布局、海陆物流联运工程、海岛开发与保护工程、沿海重大防灾减灾工程等领域强化海陆关联工程的建设。
