摘要
植被具有控制水土流失的重要生态功能。在云南高原山地生态环境下,公路沿线现有植物群落结构及功能演替状况将对该地区公路生态环境安全与水土保持具有直接或潜在的重要影响作用。选取昆明—石林高速公路沿线作为案例,结合3S技术综合运用,针对公路沿线路域植被群落开展定位样方调查,利用调查数据分析公路沿线典型植被群落的种群组成、结构层次,以及潜在演替等特性,运用生态原理运用探讨了高原山地公路沿线生态环境保护对策。
Vegetation cover is of the important ecological function of water and soil resource conservation. In mountainous region of Yunnan Plateau, roadside vegetation community condition and its succession have special significant of the direct and indirect impact on the highway environment security and water and soil conservation. Kunming-Shilin highway was selected as a study case. Helped with RS and GPS technique, field investigation on the vegetation community condition was completed along this highway. The data of 36 samples was obtained. By use ecology analysis method, the characters of vegetation population composition, constructure level and succession direction were studied and developed. Based on the primary analysis result, some proposals on vegetation conservation along this highway were brought forward.
