青海省土地集约利用与经济发展时空差异分析

以青海省土地利用变更数据和社会经济发展数据为依据，建立土地集约利用与经济发展水平评价指标体系，运用基于结构熵权法的多因素综合评价法，对青海省2000—2009年间土地集约利用度以及经济发展水平进行评价；并运用统计方法，对比分析青海省土地集约利用和经济发展的时空差异特征及其二者相关性。结果表明:从时间变化特征来看，青海省土地集约利用度和经济发展水平总体呈上升趋势，但地区之间存在差异，2003年起州（地、市）域间土地集约利用度和经济发展水平的差距不断变大；从空间变化特征来看，经济发展水平北部高于南部，全省经济发展具有显著的空间差异性，而土地集约利用度北部地区高于南部地区，由东北向西北递减，且在东北部地区，以西宁市为中心向外递减；土地集约利用与经济发展空间相关度较低，协调度较差。

Spatiotemporal Analysis of Disparities between Intensive Land Use and Economic Development in Qinghai Province

Based on data of land use and social and economic statistics of Qinghai Province, this research established an evaluation system of intensive land use and economic development, evaluated the conditions of intensive land use and economic development during the period from 2000 to 2009 by structure entropy approach and compared spatial-temporal disparities between intensive land use and economic development of Qinghai Province as well as their relevance by statistic method. As a result, from the perspective of temporal characteristics, the levels of intensive land use and economic development have enhanced. However, they varied in different regions. The gap between intensive land use and economic development has been consistently increasing since 2003. From the perspective of spatial characteristics, the level of economic development in northern areas is better than that in southern areas and the economic development in the whole province presents evident spatiotemporal disparities. The level of intensive land use in the northern areas is higher than that in the southern areas, decreasing from northeast to northwest. Moreover, in northeastern areas, it decreases outwards with the center of Xi’ning City. The relevance and coordination of intensive land use and economic development are generally low.
