小良水土流失中主要自然因子影响的灰色分析

小良地区曾是一个典型的水土流失区,现已基本上得到有效治理,为使其达到可持续发展。必须认真研究导致该区水土流失的主要因京。采取定性与定量相结合的方法,重点分析了该区的地形地势、岩土性质、森林植被、气象水文等自然因子对水土流失的影响,并运用灰色理论对影响水土流失的主要因子进行相关度分析,揭示了植被因子是造成水土流失的最主要因素,在四大因子中居于首要地位。

Grey Theory Analysis of Main Natural Factors in Xiaoliang Soil and Water Loss

Xiaoliang area, which used to be a typical area with soil and water loss, has so far been under some basically effective control. In order to maintain the sustainable development of Xiaoliang area, we must do more research on the main factor which leads to soil and water loss and its related degrees. In addition to a brief analysis of the causes of soil and water loss, and the effects on it from terrain and relief condition, geotechnical property, forest cover, and so on, further study is implemented by the correlation degree analysis using grey theory on the main factors of soil and water loss. The significant effect of the natural factors on the soil and water loss is emphasized.
