榆社县土地利用和生态服务价值变化分析

Analysis on the Change of Land Use and Ecosystem Service Value in Yushe County

关于土地利用和生态服务价值的研究一直是土地和生态方面研究的热点。在对榆社县2010—2015年的土地利用动态变化分析的基础上,应用COSTANZA等生态服务价值公式和谢高地等的生态服务价值表,计算了榆社县2010—2015年的生态服务价值变化。结果表明,2010—2015年榆社县耕地和其他用地在减少,而林地、草地、水域、建制村工矿用地、交通用地和园地都在增加;林地、草地、耕地、水域和未利用地5种土地利用类型的总生态服务价值增加了0.69亿元,但是食物生产的生态服务价值在下降;榆社县箕城镇和社城镇的生态服务价值呈下降趋势,其他乡镇的生态服务价值都呈上升趋势,其中,土地利用动态度较大的4个乡镇(讲堂乡、兰峪乡、西马乡和河峪乡)的生态服务价值增长也较大。

The research on land use and the value of ecological service has been a hot research topic in the field of land and ecology. Based on the analysis of the dynamic changes on land in Yushe county from 2010 to 2015, this paper used ecological service value computing formula to calculate the change of ecological service value in Yushe county in 2010-2015. The results showed that from^2010 to 2015, farmland and other land use reduced, while forest land, grassland, water area, industrial and mining land, transportation land and garden increased. From 2010 to 2015, the total ecological service value of forest land, grassland, farmland, water area and unused land increased by 69 million yuan in Yushe county, but the value of ecological service of food production declined. From 2010 to2015, the ecological service value of Jicheng town and Shecheng town declined, and the value of ecosystem services in other towns increased. Among them, four towns（Jiangtang township, Lanyu township, Xima township, Heyu township）with the larger dynamic degree of land use were the four larger towns of the ecological service value.
