摘要

通过野外调查和农户跟踪调查

研究了金沙江下游五官小流域综合治理措施

包括生物措施、工程措施、农耕措施及其它配套措施

并进行了生态效益、经济效益和社会效益分析。结果表明

林草覆盖率由25%提高到81%

增加了56%;年均土壤侵蚀量由2.67×104t减少到6.5×103t

减少了75.77%;粮食产量由3645kg/hm2增加至9330kg/hm2

提高了156%;人均粮食产量由282kg增加到416kg

提高了47.52%;农业总产值由41.48万元增加至439.74万元

提高了960.13%;人均纯收入由184元增加至1660元

提高了802.17%。最后总结了五官小流域综合治理的成功经验及其对金沙江下游地区小流域治理的借鉴意义。

Abstract

By field survey and follow-up investigation on famers

the technology on the comprehensive management in Wuguan small watershed in the lower reaches of Jinsha River is studied

including biological measures

engineering measures

farming practices

and other complementary measures.The ecological

economic and social benefits are further analyzed.Results showed that forest and grass coverage rate was improved from 25% to 81%

an increasing of 56% ; the average annual amount of soil erosion was reduced from 26 700 to 6 500 ton

a decreasing of 75.77% ; grain yield was increased from 3 645 to 9 330 kg/hm2

an increasing of 156% ; per capita food production was increased from 282 to 416 kg

an increasing of 47.52% ;agricultural output value was increased from 4.15 @ 105to 4.40 @ 106thousand yuan

an increasing of 960.13% ; and per capita net income was increased from 184 to 1 660 yuan

an increasing of 802.17%.In the end

the paper summarized the successful experience of the comprehensive control in Wuguan small water-shed and the referenced significance to other small watersheds in the Jinsha River region.
