三峡水库移民安置区抗御水旱灾害的措施

三峡水库及移民安置区位于川东鄂西山丘地区，这是一地区洪旱灾害频繁，经常造成农作物减产或绝收，严重地制约着农业经济发展，也不利于农村移民的生产安置，因此解决水利问题十分重要。本文以三峡区四川忠县洋渡镇农村移民试点规划为例，通过降水量、蒸发量及可蓄水量的分析计算，说明峡库区根据当地的自然条件，结合坡改工程，配套修建型蓄游泳池，完全可以最大限度地拦蓄地面径流，保持水土，抗御洪旱灾害。从而建立稳产高产农田

Flood and drought resistant measures for Three Gorges Project's resettlement area

Three Gorges reservoir area and its resettlement area are situated in themountainous zone of eastern Sichuan and western Hubei provinces,where the frequent flood and drought disasters result often in the reduction or nothing of yield of agricultural crops,and in seriously constraining the development of agricultural econorpy,and do not favour therural resettlepeent by way of agricultural production. Solving problem of the water conservancy,therefore,is very important. Taking the tentative rural resettlement planning for Yangdutown,Zhongxian county,sichuan province,in the Three Gorges reservior area as an example,through the analysis of rainfall,amount of evaporation and storable water volume,this paperexpounds that in view of its natural conditions,the surface runoff in the Three Gorges reservoir area may be,to the utmost limit,retained to conserve the soil and water and prevent theflood and drought disasters,by constructing the small scale water ponds in combination withthe changing-slope-into-terrace works. Thus, the establishment of steady-and high yield farmland, the development of agricultural economy, and appropriate.rural resettlementmay be achieved,giving rise to a stable and plentiful life to emigrants.
