摘要 在季节性干旱的江苏省东海县丘陵地区 ,地表林木覆盖率低 ,土地资源利用不合理 ,促使水土流失加剧 ,生态环境恶化。解决丘陵岗岭地区干旱缺水的途径有 :(1)采取充分利用有利地形部位 ,开挖截水沟 ,建设小型水库、水塘、大口井、小口井 ,并通过沉沙井使之连成一个完整的丘陵岗岭地以拦蓄水为主的水保工程体系 ;(2 )坚持植树、种草 ,合理利用土地资源 ,修筑梯田 ,深耕土地 ,推广等高耕种技术 ,控制水土流失 ;(3)建设井蓄、井灌相结合的蓄灌体系 。 In the seasonal arid area of upland in Donghai county, there are more erosion and degeneration of ecosystem owing to the greater difference of precipitation yearly and monthly, lower forest cover rate or using soil resources irrationally. (1) To use the advantage terrain positions fully, to dug bayberry of stopping water, to build small reservoir, water pools, big mouth wells, and small mouth wells. All of those were connected to be a soil and water conservation engineering system of upland by settling tanks; (2) To plant trees and grasses persistently, to use soil resources effectively, and build terraces, deeply plough soil, spread technique of contour cultivation, control erosion; (3) To build wells storage and irrigation system, to use surface water and groundwater sufficiently.
