- Title:
- Comprehensive Control of Soil Conservation and Its Benefit of Silt Detention in the Quanjiagou Valley
- 摘要:
- 本文对泉家沟流域在1980—1988年综合治理期间实践的各项措施及其减沙效益进行了阐述与分析。该流域以每人平均建立2.5亩基本农田为出发点，调整农林牧用地结构，将生物措施与工程措施有机地结合起来，9年间取得了明显的效益。与1979年相比较，农林牧副总产值提高4.99倍，粮食总产增长68.9%，单位面积产量提高1.3倍，农耕地退耕49.9%，林草覆盖率提高2.6倍，径流含沙量减少64.5%，土壤侵蚀模数与1979年同类地区相比降低了92.4%。
- Abstract:
- The measures of the practice for comprehensive controlling in the Quanjiagou Valley and its benefit of silt detention during the period 1980-1988 are expounded and analysed in this paper.Taking an average of 2.5 mu basic farmland constructed for each person as starting point, in this valley by regulating the structure of the land used for farming, forest and pasture and combining the biological measures with the engineering measures organically, some significant results have been achieved during these 9 years.As compared with 1979, the farmland withdrawn by 49.9%, but the total output value, total grain yield and per unit area yield increased by 499%, 68.9% and 130%, respectively; the covering ratio of tree and grass increased by 260%; the silt content of surface runoff reduced by 64.5% and the soil erosion modulus reduced by 92.4% as compared with the similar area.
