Ecological carrying capacity of the Liujiaxia reservoir

Due to harsh conditions, the ecological environment of Liujiaxia reservoir is frail and the soil erosion here is serious. It is urgent to improve the ecological environment. Ecological carrying capacity of the Liujiaxia reservoir, the Nianzigou small watershed of the north Liujiaxia reservoir and the Sanpinggou small watershed of south Liujiaxia were calculated in this study to provide theoretical support for improvement of ecological environment construction in the study area. Based on theory of ecological carrying capacity, this study established comprehensive index system, which included ecological resilience, resource carrying capacity and resource carryingpressing index. The results of this study showed that ecological resilience was unstable, and carrying capacity index of water resource was low, and soil carrying saturation was severe overloading. This study suggested that the Liujiaxia reservoir was currently unsustainable development. It is effort to develop comprehensive management measures of soil erosion to improve ecological carrying capacity of Liujiaxia reservoir in the future.
