| 摘 要： | 小江流域泥石流滩地水源充足、热量丰富,气候生产潜力(47641kghm-2)较高。本文应用加权指数和法确定了不同类型泥石流滩地(荒滩地、改良滩地和非改良滩地)土壤有效系数f(s)分别为0.405、0.684和0.594;根据生产力阶乘公式计算其气候—土壤生产潜力分别为19295kghm-2、32586kghm-2和28299kghm-2。通过实地调查验证,本文对泥石流滩地生产潜力的估算与现实生产力水平基本吻合,证明本文提出的泥石流滩地土壤有效系数切实可行。

| Abstract: | There is a good climate potential productivity (47641kg hm~(-2)) for the debris flow waste-shoal land with abundant light, heat and water resources in Xiaojiang Valley. Through the soil classification with the measure of power index summation, the results of soil available coefficients are 0.405 in wasteland, 0.594 in farm land with no-siltigation and 0.684 in improved farm land with siltigation. And the climate-soil potential productivities are 19295 kg hm~(-2), 2899 kg hm~(-2) and 32586 kg hm~(-2)respectively. Validated in field sampling, the results of land potential productivity are nearly equaled to the real productivity. Therefore, the soil available coefficients calculated in this paper are rational. |
