摘要
本文根据清江流域自然旅游资源的特色，首先提出了一套对其进行详细系统的调查方法：（１）利用遥感数字图像处理技术及航、卫片解译结果，圈出潜在景区及潜在景点；（２）详细调查、收集及整理清江流域各市、镇已有资料，填写旅游资源调查登记卡片；（３）在（１）、（２）基础上，对主要潜在景区及景点进行野外现场调研。然后，以调查结果为前提，提出了采用综合评比法、模糊数学评价方法、信息量评价方法、神经网络评价方法及地理信息系统（ＧＩＳ）应用技术对清江流域自然旅游资源进行综合分析与评价，并对这些方法的可行性进行了分析与论证。
癏uyuan' (protective embankments in lakeside areas) is the basic unit for wetland agriculture of lacustrine plain. The investigation and analysis of agricultural development were carried out in Xinxingyuan, a typical huyuan in Sihu Region, Jianghan Plain, Central China Methods of ecological engineering have been used for sustainable development of agriculture in Xinxingyuan. Firstly, a new model of water conservancy engineering with both retainment and draining of floodwater was established on the basis of micro- landforms. Secondly, new models of landuse for agriculture were applied on the basis of soil and water conditions, such as vegetables on the higher plain, rice and other food crops on the gentle slope plain, lotus and other water plants on the low plain, different kinds of fish in the open lakes and closed ponds. Thirdly,methane-generating pit will be set up for the multistage utilization of energy and substance. Finally, the wetland environment must be protected for permanent utilization of natural resources and sustainability of agricultural development.
