土地利用变化对罗甸县生态系统服务价值的影响研究

土地利用变化对区域生态系统维持其服务功能起决定性作用,对由土地利用变化引起的生态系统服务价值变化进行研究,可以为区域生态环境的保护和经济的发展提供科学依据,以使环境保护和经济的发展能够达到和谐的统一。现利用罗甸县1996～2006的土地利用变更数据,采用谢高地等(2007)计算生态系统服务价值的方法对贵州省罗甸县1996～2006年的生态系统服务价值进行了估算,并对因为土地利用变化引起的生态系统服务总价值和结构的变化进行了分析,得出罗甸县生态系统服务价值呈下降趋势,与经济的发展呈负相关关系,因此建议罗甸县在发展经济的同时,也要采取积极的生态保护措施,使环境改善和经济发展同时进行。

Study on effects of land use change on ecosystem services value in Luodian county

Land-use change plays a decisive role in regional ecosystems to maintain their service functions.Research on the changes of ecosystem services value caused by land-use change can provide a scientific basis for regional environmental protection and economic development,as well as make environmental protection coexist with economic development. Based on the data of land use change 1996~2006 in Loudian county,and using methods of Xie Gaodi,etc. (2007) this paper estimated the value of ecosystem services 1996~2006 in Luodian of Guizhou Province and analyzed changes of total value and structure of ecosystem services caused by land use change. It turned out that the value of ecosystem services in Luodian declined and it had a negative correlation with the economic development.We recommended that proactive measures should be taken for ecological protection while developing economy so as to improve environment and develop the economy at the same time.
