摘要
公路建设的生态环境保护是开发建设项目中一个极其重要的任务。从土地资源、水土流失、生物资源、景观等环境要素对湖南彭家坳至集里高速公路工程建设引起的生态环境问题进行了分析与评价。认为公路建设对于土地利用、土地利用类型等因素的影响不大,而对于土壤理化性质及水土流失等影响较大;对于生物资源的影响不大;新的景观环境可以增加各种流的连通度,但也造成景观破碎程度增加。针对公路建设形成的生态环境影响形式与影响程度,结合公路建设项目区的自然环境特征,提出了科学的、合理的、切实可行的生态环境修复技术措施。
Eco-environmental conservation in road construction is an strikingly important task in exploitation projects. Based on land resources, soil erosion,biological resources,landscape environment,the eco-environment problems caused in highway construction project in Hunan Pengjiaao to Jili are analyzed. It has little effect on land use, land-use type and biological resources ,and has big influence on soil physic and chemistry quality and soil erosion. New landscape environment can enhance the connectivity of flow,meanwhile,it can increase landscape frangmentation. According to the form and degree of effect for eco-environment and natural environment characteristic in road construction project area, some scientific, reasonable and feasible eco-environment restoration measures are provided.
