保定市土地压力动态分析

Dynamic Change Analysis of Land Pressure in Baoding City

自2017年设立雄安新区以来,保定市土地资源的可持续利用愈加重要。为提高保定市土地利用效率,满足京津冀地区协同发展的需求,以保定市2013、2015、2017年Landsat8遥感影像解译成果为基础,针对粮食生产、经济发展和生态建设三个方面,运用土地压力定量评估方法,探讨了保定市不同县区及不同时期土地压力状态的变化情况,分析了土地压力的成因及其可持续利用的途径。

Since the establishment of Xiong’an New Area in 2017, the sustainable utilization of land resources in Baoding has become increasingly important. In order to improve the land use efficiency of Baoding and meet the needs of the coordinated development of Beijing, Tianjin and Hebei, based on the interpretation results of Landsat 8 remote sensing images of Baoding in 2013, 2015 and 2017,this paper discusses the changes of land pressure in different counties and regions of Baoding in different periods by using the quantitative evaluation method of land pressure in three aspects of grain production, economic development and ecological construction. The causes of land pressure and the way of sustainable utilization are analyzed.
