| 摘 要： | 为了探讨川中丘陵区小流域综合治理模式,采用农耕、生态、工程措施相结合的方法对川中丘陵区9市(州)所辖的37个县(市、区)212条小流域综合治理5年后的情况进行调查分析,结果表明:1)土地利用结构的调整使25°以上坡耕地面积减少49.28倍,人均基本农田面积增加0.21倍,农业总产值和人均纯收入分别提高37.91%和25.92%,泥沙拦蓄量提高5.41倍,径流拦截能力提高2.19倍;2)生态工程措施使林业总产值增幅达到138.13%,水利水土保持工程提高了农田水分利用效率及保护机制,治理后,泥沙拦蓄能力提高近5倍,径流拦蓄能力提高近3倍;3)社会效益成果显著,以粮食消费为标准的环境人口容量提高5.97%,以价值消费为标准的环境人口容量提高37.97%。说明川中小流域的综合治理工作卓有成效,这离不开当地农民的支持和配合,其中农耕措施所带来的经济效益最明显,可作为流域综合治理的切入点。 |

| Abstract: | To achieve comprehensive control model in small watersheds,in the hilly area of Sichuan Province,212 small watersheds belonging to 37 counties managed by 9 cites were comprehensively treated using integrated farming,ecological and engineering measures for 5 years.Results showed that： 1） As against the original status,the area of farmland with slope over 25° decreased 49.28 times,per capita basic farmland area increased 0.21 times,gross agricultural output value and per capita net income improved by 37.91% and 25.92% respectively,the amount of sediment interception improved 5.41 times,and the ability of runoff interception improved 2.19 times.2）The increase amplitude of forestry total output value reached to 138.13% brought by ecological measures.Water conservancy and soil and water conservation projects could improve the water use efficiency and protective mechanism of farmlands.After 5 years treatment,the amount of sediment interception improved nearly 5 times,while the ability of runoff interception improved nearly 3 times.3）The social benefits got remarkable results.Environmental population carrying capacity increased by 5.97% by using grain consumption as the standard,while increased by 37.97% by using value consumption as standard.It indicated that the comprehensive treatment on these small watersheds has got fruitful outcome supported and cooperated by local farmers.Farming measures could bring significant economic efficient,so it should be the starting point of watershed comprehensive management. |
