摘要
从土地利用转移类型、空间格局变化定量分析、动态变化预测模型等方面分析近20年都安土地利用变化,进而对其生态环境质量变化进行定量分析,得出结论:都安各乡(镇)生态环境质量改善与恶化在很大程度取决于裸岩地扩展与收缩,土地利用时空变化与区域生态环境质量的区域差异有很大相关性。
First of all, the land use change in Du＇ an Yao Autonomous County of Guangxi lately 20 years is analyzed from the aspects including use transfer type, spatial pattern change quantitative analysis, forecast model of dynamic change, etc; Moreover, the paper takes a quantita, tive analysis on their eco-environmental quality change. Amelioration and depravation of eco- environmental quality in the various villages and towns of Du＇an result from the naked land＇s enlarging and shrinking, and it can bring into the large relationship between land use temporal-spatial change and regional difference of eco-environmental quality.
