Effect of impervious surface on stormwater runoff pollution in urban tourist attractions;

城市旅游区暴雨径流污染过程中的不透水面效应

Removal of rural land cover types such as soil,water,and vegetation and their replacement with common urban impervious surface materials such as asphalt,concrete,and metal have significant environmental implications.

城市化的一个重要表现就是不透水面分布比率的上升,城市内部不透水面分布是城市生态环境的一个重要指标。

As a major component of the Ridd s vegetation-impervious surface-soil(V-I-S) model,urban impervious surface is important in monitoring urban expansion and understanding impacts from human activities on the environment.

作为Ridd V-I-S模型中的一个重要组成部分,城市不透水面在监测城市扩展和解释人类活动对生态环境的影响起着非常重要的作用。
