摘　　要：采用土地利用综合动态度模型、土地利用转移矩阵及景观格局指数对玉屏县2000—2015年土地利用数据进行分析处理。结果表明:整个研究时期内土地利用变化的核心是建设用地、耕地、林地、草地及水域用地。建设用地和水域用地呈现逐年增加的趋势,耕地呈现逐年减少的趋势;土地利用综合动态度呈先缓后快增加的趋势。景观破碎化程度呈现上升发展趋势,景观多样性指数先增加后降低;均匀度指数在研究时段内有波动,总体上有所提高;蔓延度指数和优势度指数呈现下降趋势;耕地、林地、草地及建设用地的分离度、破碎度、分维数指数呈现递增趋势发展。In this study,we adopted the integrated dynamic model of land use,the transfer matrix of land use and the landscape pattern index to analyze the land use data of Yuping from 2000 to 2015. The results showed that,the main change of land use in this period was the change of construction land,cultivated land,forest land,grass land and waters. While the area of construction land and waters increased year by year,the area of cultivated land decreased. The integrated dynamic degree of land use increased with a slow-quick trend. The degree of landscape fragmentation increased,and the landscape diversity index first increased,then decreased. The evenness index fluctuated,with an overall increasing trend. The contagion index and the dominance index decreased. The separation degree,fragmentation degree and fractal dimension index of cultivated land,forest land,grass land and construction land increased.
