英文摘要	河口三角洲湿地生态环境保护和区域开发的矛盾突出,对湿地生态圈健康和栖息地生态功能产生直接而强烈的影响.健康的河口三角洲湿地生态圈是由自然过程的连续性、生态系统的连通性、生境的异质性以及食物网的多样性等多种因素共同决定的.本文讨论了健康湿地生态圈构建的基础理论,综述了景观生态网络构建、水文连通性网络构建、食物网构建以及生境异质性栖息地营建的理论与方法.在区域和景观尺度上,以土地利用-生态系统完整性为主线,阐明了湿地破碎化对湿地生态功能的影响,特别强调景观完整性、水文连通性对湿地栖息地的影响;在生态系统和群落尺度上,以食物网-生态系统稳定性为主线,强调食物网多样性、生境异质性对湿地生物圈构建的支撑作用.基于景观完整性、水文连通性、生境异质性和食物网多样性构建健康湿地生态圈,可为湿地生态环境保护和建设提供科学依据和技术支撑.
中文摘要	The health of wetland ecosphere in an estuarine delta is determined by many factors,such as continuity of natural processes,ecosystem connectivity,habitat heterogeneity,and food web diversity. The contradiction between ecological and environmental protection and regional development in the estuarine delta is becoming more and more prominent. A series of man-made and natural processes directly and indirectly resulted in habitat fragmentation of wetlands,which has direct and strong impacts on the ecosphere health and the habitat function of wetlands. In this paper,we provided a perspective on researches on the basic theory of healthy wetland ecosphere,landscape ecological network system,hydrologic network construction,key food webs,and habitat heterogeneity.At the regional and landscape scales,with the linkages between land use and ecosystem integrity as the main line,we clarified the influences of habitat fragmentation on wetland ecological functions,especially the effects of landscape integrity and river connectivity on wetland habitat. At the community and ecosystem scales,emphasis should be given on the relationship between food web and ecosystem stability,especially the supporting role of food web diversity and habitat heterogeneity on the construction of wetland biosphere. Further efforts should focuse on the wetland habitats construction based on landscape integrity,hydrologic connectivity,habitat heterogeneity and food web diversity.These efforts could help to develop and optimize the theory and method of constructing wetland ecosphere and enhancing its ecological function,and promote the sound development of regional ecological environment and resource utilization in estuarine deltas.
