摘要
以重庆市40个区县1999—2006年土地利用状况为依据,结合其自然、社会经济条件选择土地利用经济效益评价指标,运用多元统计中的因子分析法对重庆市40个区县8 a的土地利用经济效益状况进行了分析。(1)土地利用经济效益在各年内不同区县有较大的差异:效益较好的区县大多是经济发展好的区县,主要是主城区及其经济辐射较强的区县;而效益较差的区县的经济则落后一些,主要是比较偏远的山区;这种差异在年间呈现逐步增长的趋势;(2)1999—2006年各个区县的土地利用经济效益呈现逐步提高的趋势,区县集中分布的范围也发生相应变化:分布在高效益区的区县越来越多,分布在低效益区的区县相应减少。针对上述分析结果提出了提高土地利用经济效益建议和措施。
Based on the landuse status and the natural and socio-economic conditions of 40 districts and counties in Chongqing City from 1999 to 2006, the spatial-temporal variation of landuse economic efficiency of the districts and counties are analyzed by selecting evaluation indexes and using the factor analysis of multivariate statistics. Results show that the landuse economic efficiency in different districts and counties differs greatly. The districts and counties with better landuse economic efficiency are mostly in good economic development and they are the main urban area and districts within its economic radiation zone. The districts and counties with poor landuse economic efficiency are backward and they are mostly located in the relatively remote mountain area. Moreover, the difference is displaying a growing trend. The landuse economic efficiency in various districts and counties displays an improved trend. Number of districts and counties with high efficiency increased steadily. In the light of the results from analysis, the authors propose some suggestions and measures to enhance landuse economic efficiency.
