土地利用变化及生态系统服务价值响应

On the Change of Land Use in Damao Banner and the Responding to Its Ecological System Service Value

本文采用土地利用动态度、土地利用综合指数这两个定量化模型,对2003-2010年内蒙古包头市达茂旗的土地利用变化及由土地利用变化所引起的生态系统服务价值的变化进行了分析。结果表明,达茂旗土地利用结构变化显著,总体的土地利用程度逐年降低,生态系统服务价值也随着当地经济的发展逐渐下降。因此,今后达茂旗的发展一定要提高土地利用效率,注重生态环境质量,合理规划土地利用结构,从而实现土地资源可持续利用和生态、社会、经济的可持续发展。

With the two quantitative model of LUDI（ Land Use Dynamic Inde, x） and the comprehensive Index for land use, this paper analyzes the change of land use in Damao Banner, Baotou, Inner Mongolia and the change of ecological system service value due to it. It proves that the change of land use structure of Damao Banner is obvious. The overall land use standard is decreasing annually and the ecological system service value is decreasing with the local economic development. Therefore, the future development of Damao Banner should focus on improving land use efficiency, paying attention to ecological environment quality, planning land use structure rationally so as to realize the sustainable use of land resource as well as the sustainable ecological, social and economic development.
