| 摘 要： | 作者于八十年代中期实地考察了新安江上游的环境质量。本文对该流域的水土流失程度和形成原因进行了初步探讨。该流域存在有四种形成水土流失的潜在因素即地形地貌特殊,降雨集中且强度大、土垠质地低劣、温差变动幅度大。近三十几年来,该流域水土流失日益加剧,这主要是流域的植被、土垠、水分三个生态因子失去了动态平衡,生态环境遭到了严重的破坏。

| Abstract: | This paper writers joined activity on estimation of enviro - mentrol guahty in the upper reaches of Xin An River durirng middle 80years. The paper has primary surveyed reason for soil erosion in the upper reaches. There are tour potential facts on soil erosion in the upper reaches, special land shape and lardlooks;close falling wa ter and great intensity; bad soil condition; big temperature: difference size. Recent 30year' s ,soil erosion in the upper reaches is more and more increasingly,three ecoligi cal facts of nature vegetation. Soil and water in the upper reaches have lost balanceecological enviroment has been greatly damaged. |
