高速公路环境影响评价样方调查研究—以昆明绕城高速公路为例

The Research of Simple Investigation for Highway Environmental Impact Assessment——As an Example of the Highway Circling Around Kunming

高速公路建设对生态环境和水土保持的影响较大。作为环境影响评价的一个重要手段,样方调查可以对这两种影响的程度进行定量或半定量的分析。生态环境样方调查主要是测算生态系统参数,掌握生态特征;水土保持样方调查主要是确定土壤侵蚀强度,预测水土流失。以昆明绕城高速公路为例,具体说明两种调查方法的应用,总结讨论两种调查方法的特点。

It is important to ecology environment and soil and water conservation. As a useful instrument of EIA, simple investigation can analyze these influences quantificationally and semi - quantifieationally. Simple investigation of ecology environment calculates parameters of ecology system and gain ecology characteristics, Simple investigation of soil and water conservation calculates intensity of soil erosion and forecast soil and water losses. As an example of the highway circling around Kunming, this paper explains the application of two investigations and discusses respective characteristics.
