摘要
分析木美地下河流域石漠化的现状和特征,认为目前木美地下河流域整体上处于中度、重度石漠化状态;石漠化对流域内土壤性质的影响还不太明显;流域内的植被以灌丛为主,被破坏严重,分布零星,但是植被的演替同时存在顺向和逆向两种情况,只要控制好人为干扰因素,可以实现植被自然恢复;流域内可供开发利用的水源共有12处,可以解决一些洼地旱涝交替的局面。建议利用植被群落自身的顺向演替能力,通过封山来育林,用工程手段治理地下河,使水资源在空间和时间上重新分配等措施来治理木美地下河流域的石漠化。
The rock desertification in Mumei underground river basin is at primary stage.The soil characters in the basin are not affected obviously by the rock desertification.The bush clusters are dominant in the vegetation,and distribute in scattering,and damaged heavily.There are two directions of sequence and converse successions in the vegetation,and 12 spots of water resources that can be used.The better way to father the rock desertification is to promote the sequence succession of vegetation in the basin by sealing mountain passes to develop the forests and artificial engineering.
