基于土地利用变化的扶余市生态系统服务价值研究

Study on Ecosystem Service Value of Fuyu City Based on Land Use Change

在社会经济快速发展和城市化进程不断加快的背景下,研究土地利用变化对生态系统服务价值的影响程度,对充分了解区域生态环境的变化情况以及全面提高社会经济的可持续发展水平具重要意义。根据扶余市2010~2015年土地利用数据,运用土地利用动态度指标和土地利用程度综合指数及变化模型,对扶余市土地利用变化情况进行分析;利用生态服务价值系数,定量计算扶余市的生态系统服务价值并对生态系统服务价值敏感性进行了分析。结果表明,扶余市土地利用处于发展阶段,具体表现为建设用地增加,其余用地类型面积逐年减少,扶余市生态服务价值也表现为逐年减少的态势,生态环境受到一定程度的威胁,为扶余市今后社会发展过程中进行土地利用结构和布局安排以及自然环境保护工作提供指导。

With the rapid development of social economy and the accelerating process of city background, influence degree of land use change on the ecosystem service value, has very important significance to fully understand the change of regional ecological environment and improve the overall level of sustainable development of social economy. Based on the land use data of Fuyu city in 2010 and 2015, the land use change of Fuyu city was analyzed by using the land use dynamic index and the land use degree index and the change model. The ecological service value coefficient of Fuyu city was used to calculate the ecosystem service of Fuyu city The value and the sensitivity of the ecosystem service value were analyzed. The results showed that the development of land use in Fuyu city, the specific performance of the increase of construction land, other land types area decreased year by year, the ecological service value of Fuyu city also showed a diminishing trend, the ecological environment has been a certain degree of threat, the results of this study can be for Fuyu city in the future social development in the process of land the structure and layout arrangement and natural environmental protection work has certain guiding significance.
