摘要
借鉴生态学中生物种群的生态位理论,运用生态位数学测度模型,对重庆市都市区1998-2005年土地利用类型的变化做了分析,结果表明:①都市区农用地与建设用地生态位差较大,经济发展和城市化进程更加剧了建设用地占用农用地的速度和强度;②就生态位变化而言,都市区内各个区县又有所不同.探讨了土地可持续利用的方法.
The niche theory in biological sciences is used to analyze the change in land use patterns in the urban area of Chongqing during 1998 2005. The results are as follows： firstly, differences exist between cultivated land niche and non-cultivated land niche; secondly, the cultivated land niche of the districts of Beibei, Banan and Yubei are higher and the non-cultivated land niche of the districts of Yuzhong, Dadukou, Jiangbei, Shapingba, Jiulongpo and Nan＇an are higher; and thirdly, the approach to sustainable land use is discussed.
