- 摘要:
- 黄土高原多沙粗沙区的形成，既受自然地带性和非地带性因素的影响，又受历史时期人类活动和社会经济发展的作用。而自然因素奠定了黄土高原水土流失的基本格局。以临界理论为依据，以环境经济学等方法，建立了多沙粗沙区流域的环境库兹涅茨曲线，用该曲线的拟合方程，计算出各流域单元治理人为加速侵蚀所需的年限，从而评估高原多沙粗沙区水土流失治理前景。
- Abstract:
- The formation of the area with abundant and coarse sediment in the Loess Plateau is affected not only by the factors with natural belt traits and non-belt traits but also historical human activities and socio-economic development. And natural factors laid a basic pattern for the water and soil loss in the Loess Plateau. According to the threshold theory and the theory of environmental economics, an environmental kuznets curve of the drainage with abundant and coarse sediment was built up and the years needed to harness the artificial acceleration erosion for each drainage unit calculated by the fitted equation of the environmental kuznets curve to assess the prospect on the harness of water and soil loss in the area with abundant and coarse sediment.
