【摘要】 在调查分析伊犁低山丘陵区水土流失特点的基础上,研究了该区小流域水土保持措施的空间配置。结果表明:伊犁低山丘陵区水土流失主要表现为以水力侵蚀为主的多种土壤侵蚀类型作用下的坡面侵蚀和沟道侵蚀。针对其水土流失特点,伊犁低山丘陵区小流域水土保持措施优化配置为:以生态修复为主,上游地区封禁保护;中游地区种植水保林和经济林带,建立生态缓冲带;下游水平沟种草。通过综合治理开展水土保持生态环境建设,至2012年底,伊犁低山丘陵区治理程度达到77.33%,林草覆盖率48%,改善了当地生态环境。更多还原

【Abstract】 Based on the investigation and analysis of the soil erosion characteristics of small watershed at low hill area in Yili,the research was made for space configuration of water and soil conservation measures. The results showed that the entire erosion rest mainly on water erosion for a variety of mainly,the type of soil erosion of sloping land under erosion and channel erosion. Accordding to the characteristics of small watershed in Yili,the comprehensive management was given for Small Watershed at Low Hill Area in Yi Li,by restoring the ecological environment in riverhead of Yili,establishing the ecological buffer region in middle reaches by planting conservation forest and economic trees,and using the prevention measures in upstream,meantime planting grass in horizontal ditches in downstream. By the end of 2012,the harnessment degree in Yili watershed had reached to77. 33%,the coverage rate of vegetation was 48%. The construction of ecological environment in Yili had been improved.更多还原
