甘州区土地利用格局变化及生态服务价值变化评价

生态系统服务功能价值评估研究是可持续发展评估研究的关键内容和焦点,通过分析甘州区土地利用及其变化,并在此基础上,对甘州区生态服务功能价值评价进行研究。通过研究分析,结果表明:2005~2020年间,甘州区土地利用格局变化总体趋势为少数几种土地利用类型占主导地位的情况得到缓解;土地利用均匀度指数略微有所升高,说明社会经济的发展较2005年相比更为平衡;土地利用多样化程度也稍有增加。而这一变化直接影响到生态服务功能价值的变化。甘州区生态用地的结构和布局规划合理,能够满足社会经济发展和生态建设对生态用地的需求。期望通过建立环境友好型土地利用模式,优化生态用地结构与强化土地生态功能,以确保生态安全目标的实现。

Evaluation of Changes to the Pattern of Land Use and the Ecosystem Service Values in Ganzhou District

The research of the Ecosystem Services Valuation(ESV) is the key to the sustainability assessment.On the basis of the Analysing the changes of land use in Ganzhou District,did some research on the evaluation of the ecosystem service values.The results showed that between the year 2005 and 2020,the type that a few kinds of land use which dominant is eased.The index of land use uniformity rose slightly,which indicate the social economic development is more balanced than 2005.The diversification of the land use is increased slightly too.These changes will influence the evaluation of the ecosystem service value directly.The structure of the Ecological land use and the layout planning in Ganzhou District are reasonable,can meet the demand of the social and economic development and ecological construction.Expect through establishing the environment-friendly land use pattern,optimizing the ecological land use structure and aggrandizing the land ecological function,to ensure the ecological security goals.
