康定县退化草地空间分布与治理对策浅析

Analysis of Spatial Distribution and Management Measures of Degraded Grassland in Kangding County

草地是康定县绿色植被生态系统的主体,是保持康定生态平衡的重要一环。基于对康定县的草地退化情况进行评价,依据退化程度评价为4级,即无明显退化草地、轻度退化草地、中度退化草地以及重度退化草地。根据评价结果,结合研究区的高程、坡度、坡向、居民点信息,分析康定县退化草地的分布情况,并对草地退化原因进行了分析,提出了退化草地的恢复与治理对策。

Grassland is the principal part in Kangding green vegetation ecosystem and is an important part to maintain the ecological balance of Kangding. In this paper, evaluation was made dation in Kangding based on remote sensing and GIS technology. The grassland grades including inconspicuously degraded grassland, slightly degraded grasslan on the grassland degra- was evaluated into four d, moderately degraded grassland and severely degraded grassland. Then according to the evaluation results, degraded grassland spatial distribution was analyzed by combining and settlements. Moreover, reasons of grassland ment countermeasures of degraded with information of elevation, slope gradient, slope aspect degradation were discussed, and restoration and manage- grassland were also proposed in this paper
