【摘要】：雄安新区是千年大计、国家大事。深入分析雄安新区土地利用的现状空间特征,对于推进新区高起点高标准规划建设具有重要意义。本文基于多时相Landsat-TM/ETM+/OLI遥感数据解译,分析了雄安新区土地利用的总体特征,并重点研究了建设用地节约集约利用的潜力和耕地质量的区域差异。提出了雄安新区起步区的三个可能备选方案,并分析了其各自利弊。研究表明,雄安新区土地呈"六田、二建、一水、半分林"特征;现状建设用地尤其是农村建设用地的节约、集约利用潜力较大;耕地质量及其利用强度的空间差异显著,容城、安新耕地质量好,复种指数高,分别达1.92和1.87,雄县耕地质量较差,复种指数明显偏低,仅为1.32。综合考虑起步区的相对完整性、未来发展的可拓展性、与周边县市的兼顾性和防洪安全性,统筹权衡优质耕地保护和建设用地征收拆迁成本等因素,本文建议以位于容城东部与安新、雄县交接处的"中方案"作为起步区的优先方案。针对新区建设需要大量占用土地的现实需求,本文建议优先通过农村(含乡镇)集体建设用地的征收与节约集约利用解决;新区建设不可避免会占用耕地,建议优先安排占用等级较低的耕地,尽量保护优质高产耕地;建议合理确定土地征收与征用时序,分类施策,优化土地资源管控。同时指出,雄安新区大部分地势相对较低,新区规划、选址和建设需要高度关注防洪排水问题。
[Abstract]:Xiong an New area is a millennium plan, a national event. It is of great significance to analyze the present situation and spatial characteristics of land use in Xiong'an New area for promoting the planning and construction of high starting point and high standard in Xiong'an New area. Based on the interpretation of multitemporal Landsat-TM/ETM / OLI remote sensing data, this paper analyzes the general characteristics of land use in Xiong'an New area, and focuses on the potential of saving intensive use of construction land and the regional difference of cultivated land quality. Three possible options for the starting area of Xiong'an New area are put forward, and their respective advantages and disadvantages are analyzed. The study shows that the land in Xiong'an New area is characterized by "six fields, two constructions, one water and half forest"; the present construction land, especially the rural construction land, has a great potential for intensive utilization; the spatial difference of cultivated land quality and its utilization intensity is significant. In Rongcheng, Anxin cultivated land is of good quality and the index of multiple cropping is high, reaching 1.92 and 1.87 respectively. The quality of cultivated land in Xiong County is poor, and the index of multiple cropping is obviously low, which is only 1.32. Taking into account the relative integrity of the starting area, the expansibility of future development, the consideration of the surrounding counties and cities and the safety of flood control, the overall balance between the protection of high-quality cultivated land and the cost of expropriation and removal of construction land, This paper suggests that the "middle plan" located in the eastern part of Rongcheng and Anxin, Xiong County as the priority scheme in the starting area. In view of the realistic demand that the construction of the new area needs a large amount of land, this paper suggests that priority should be given to solving the problem of expropriation and intensive utilization of the collective construction land in the countryside (including villages and towns), and that the construction of the new area will inevitably occupy the cultivated land. It is suggested that priority should be given to the cultivated land of low occupation grade, and the high quality and high yield cultivated land should be protected as far as possible, and the timing of land expropriation and expropriation should be reasonably determined, the policies should be classified and applied, and the land resource At the same time, it is pointed out that most of the topography of Xiong'an New area is relatively low, and the planning, site selection and construction of the new area need to pay close attention to flood control and drainage problems.
