长江中下游流域滩地可持续利用研究

随着工业化、城市化进程的不断推进，长江中下游地区人地矛盾日趋尖锐，人均耕地已低于粮农组织规定的警戒线。而90余万hm2的滩地资源则因血吸虫病、产权与使用脱节以及管理困难等原因致使其大部分一直处于荒芜和半荒芜状态，亟待治理和开发。通过剖析长江中下游流域滩地特点及利用现状，分析其出现的生态环境问题及产生原因，提出滩地综合治理和可持续利用的原则及治理对策，认为开发利用滩地资源应与河道整治、经济建设、血防工作及湿地保护相结合，因地制宜、科学规划、分步实施，逐步建立一个集生产、防护与游憩于一体的多功能、多效益的综合体系，更好地发挥黄金水道对整个地区乃至整个国家国民经济建设的作用。

RESEARCH ON SUSTAINABLE USE OF THE MIDDLE AND LOWER BEACH LAND OF THE YANGTZE RIVER

As the industrialization and urbanization continue to move forward,contradiction between people and land in the Yangtze River region is getting acute and per capita arable land has fallen below the warning line provided by FAO.Due to schistosomiasis,management difficulties,as well as disconnection between property and utilization and other reasons, most of 900 thousand hectares of beach land resources had been in desert and semi desert state,in urgent need of governance and development.In this paper,the characteristics and use status of middle and lower reaches of the beach areas in the Yangtze River region and its eco environmental problems and causes were analyzed.The principle of comprehensive management and sustainable use was put forward.Development and utilization of beach land resources should be combined with river regulation,economic development,schistosomiasis control and wetland protection.In light of local conditions,one integrated system covering production,protection and recreation should be set up by scientific planning step by step.Thereby the golden waterway could play important part in the economic construction of the region and the nation.〖HJ1〗
