【摘要】 以生态学理论为基础,选取以金昌—武威高速公路为研究对象,调查高速公路周围影响区域植被种类与盖度,计算高速公路修建后生物丰度指数、植被覆盖指数、土地退化指数、水网密度指数、环境质量指数以及生态环境状况指数;采用综合指数评价法分析了该段高速公路建设对其周边生态环境的影响程度,并对缓解公路建设影响、维持区域生态环境功能和可持续利用自然资源应该采取的措施做出了较科学的分析和评价。更多还原

【Abstract】 Based on the ecological theory,the Jinchang-Wuwei Expressway was selected as the research object.The vegetation types and coverage of the affected areas around the expressway were investigated.The biological abundance index,vegetation cover index,land degradation index and water network density index,environmental quality index and ecological environment status index were calculated.By using the comprehensive index evaluation method,the influence degree of the highway construction on its surrounding ecological environment was analyzed,and the measures to be taken for the sustainable use of natural resources are proposed to alleviate the impact of road construction and maintain regional ecological environment were made more scientific analysis and evaluation.更多还原
