桂阳高速公路对岩溶湿地的影响及对策

公路是国民经济的重要基础设施,修建高等级公路,逐步提高公路网的密度是经济、社会可持续发展的基础.湿地具有调节气候、保持水源、净化水质、蓄洪防旱、维护生物多样性等独特功能,保护湿地资源已成为人类社会刻不容缓的任务.以正在建设中的桂梧高速公路桂林-阳朔段为例,介绍了桂阳高速公路和会仙岩溶湿地的基本概况,从遥感的角度分析了工程建设对湿地环境产生的影响,并提出了公路运营期间合理保护湿地资源的对策.

Influence on Karst Wetland Caused by Guiyang Highway

Highroads are the main infrastructure of national economy.In order to keep the society economy continuous development,it is necessary to build more highways and increase the density of road meshwork.Wetlands possess many unique functions,such as regional climate regulation,water resource protection,water quality purification,flood and drought control,biolldiversity maintenance,and to protect wetland resource has become more and more imperative and important.Taking the highway construction of Guilin to Yangshuo as an example,the situation of Guiyang Highway is introduced that is still being built and Huixian Karst Wetland,and analyzed the influence on wetland environment caused by highway construction with the help of remote sensing.Some related control measures are put forward to improve the protection of wetland resources.
