【摘要】：以重庆市忠县为例,构建土地利用转移矩阵模型和重心模型,采用区域生态环境质量指数、土地利用生态贡献率指数等分析了忠县土地利用时空转型特点及其重心演变规律,揭示出忠县区域生态环境变化趋势。结果表明:11990—2015年,忠县土地利用转型特征主要表现为生态用地面积显著增加,生活用地面积不断扩大,生产用地面积明显减少。21990—2015年,生态用地和农业生产用地重心在空间上变化不明显,城乡生活用地和工矿生产用地重心发生明显偏移。31990—2015年,忠县总体生态环境质量指数稍有增加,区域内生态环境改善与恶化趋势并存,生态改善趋势大于恶化趋势。
[Abstract]:Taking Zhongxian County of Chongqing as an example, the land use transfer matrix model and barycenter model were constructed, and the characteristics of land use space-time transformation and the law of its center of gravity evolution were analyzed by using the index of regional ecological environment quality and the index of ecological contribution rate of land use. The change trend of regional ecological environment in Zhongxian County was revealed. The results showed that the characteristics of land use transformation in Zhongxian County from 1990 to 2015 were as follows: the ecological land area increased significantly, the living land area increased, and the production land area decreased significantly from 1990 to 2015. The center of gravity of ecological land and agricultural production land did not change obviously in space, and the center of gravity of urban and rural living land and industrial and mining production land shifted obviously. 3 from 1990 to 2015, the overall ecological environment quality index of Zhongxian increased slightly. The trend of ecological environment improvement and deterioration coexisted, and the trend of ecological improvement was larger than that of deterioration.
