茂兰自然保护区板寨地下河系统的水文地质特征

Hydrogeologic characteristic of Banzhai Subterranean River Stream System in Maolan Nature Reserve

贵州茂兰自然保护区板寨地下河系统是一个边界封闭的地下水系统,板寨地下河的汇水面积较小,水污染程度低,面临的主要污染来自农业生产。在研究该区水文地质条件的基础上,分析出板寨地下河的主要径流通道,圈定板寨地下河的汇水面积,通过对该系统水化学特征地分析,进一步证实了板寨地下河系统的地下径流途径和地表汇水范围,为科学地保护板寨地下河乃至整个茂兰自然保护区提供依据。

Banzhai subterranean stream in Maolan nature reserve of Guizhou is a groundwater system which boundary is closed, the catchment area of Banzhai subterranean river stream is small, compared with other area the water pollution level is lower, the main pollution source come from agricultural production. Based on the researching of the hydrogeologic condition of the area, we analyze the main runoff channel, and states the catchment area of Banzhai subterranean stream. From the analysis of hydrochemistry characteristic, we further substantiate the groundwater runoff channel and the surface catchment scope. Above all, the thesis has provided necessary data that can scientifically protect Banzhai subterranean river stream and even the entire Maolan nature reserve.
