基于3S技术的城乡一体化进程监测评价方法及应用——以浙江嘉善县为例

基于3S技术构建城乡一体化进程监测评价指标体系和综合评价模型,以浙江嘉善县为例开展监测评价。结果表明：嘉善县各乡镇城乡一体化程度综合指数差值不超过1.95倍,发展较均衡;2003~2015年间人口城镇化率上升了20.4%;各乡镇内部道路系统密度差异由18倍缩小到4.3倍,城乡道路网络系统由单核向多核演变;各乡镇城乡收入差距在2倍之内且呈缩小趋势;城乡居民地空间布局比较均衡,城镇带动周边农村居民点快速发展。该指标体系在客观性和空间表达等方面发展了城乡统筹定量研究方法。

Evaluation Method and Its Application of Urban-rural Integration Progress Based on 3S Technology: A Case Study of Jiashan County,Zhejiang

At present, most studies in urban-rural integration conduct quantitative researches using statistical indexes, which are fairly subjective. Through 3S technology, this study advanced an evaluation index system and comprehensive evaluation model of urban-rural integration, based on which a series of systematic monitoring work was carried out in Jiashan, Zhejiang Province. The results showed that the maximum composite index of urban-rural integration degree was only 1.95 times larger than the minimum one, which showed a great balance; During 2003-2015, the rate of urbanization population has increased by 20.4%; The difference between the maximum and minimum value of road network density decreased from 18 times to 4.3 times, and the road network system changed from single-core to multi-core; The income gap between urban and rural was well controlled within 2 times with a narrowing trend; The spatial distribution of urban and rural habitation was relatively uniform, and the rapid expansion of urban areas would boost the development of surrounding rural residential areas. The index system has helped develop the quantitative methods of urban-rural integration studies in terms of objectivity and spatial expression.
