    雄安新区耕地质量空间分布特征与建设占用推荐分区

    Spatial distribution characteristics and construction occupancy zoning of cultivated land quality in Xiongan New Area

    • 摘要: 为识别雄安新区耕地质量现状空间特征,以2016年雄县、容城县、安新县的耕地质量等级补充完善成果作为基础数据,应用面积加权平均法、等别均值二分法、局部自相关分析法,揭示新区耕地等别的空间分布特征,分析不同尺度的耕地等别特征、平均等别、质量差异以及新区耕地质量空间聚集特征,并以此作为建设用地占用耕地分区的基础。研究表明雄安新区耕地质量分布在6~14等之间,平均等别为9.42等,总体上以中等地为主;耕地质量离差在-3.42~4.58之间,质量离散程度较低耕地主要分布在新区北部和东部,离散程度较高的耕地主要分布在中部和南部;耕地质量在空间分布上表现出较强的正相关性,LL型(高等地聚集型)耕地主要分布在新区东北部和西南部,HH型(低等地聚集型)耕地主要分布在新区西北部、东部及南部的部分区域。根据耕地局部空间自相关类型制定了建设占用耕地区域划定规则,将新区耕地划分为建设优先占用区、建设后备占用区、耕地保持区和水系调控区等建设占用耕地推荐分区,并对其合理性进行了分析。基于以上结果以及新区建设不可避免会占用耕地的现实,建议优先安排占用建设优先占用区耕地,尽量保护耕地保持区和水系调控区的现状。

       

      Abstract: Abstract: Xiong'an New Area was set up on April 1, 2017 and became a hot spot for scholars. This research aimed to distinguish the spatial distribution characteristics of cultivated land quality gradation in the Xiong'an New Area, to provide the scientific basis for construction land selection. This paper discussed the spatial distribution characteristics of cultivated land quality gradation, and analyzed the characteristics and average grade of cultivated land quality at different spatial scales, as well as the spatial agglomeration characteristics of cultivated land quality gradation, on the basis of cultivated land quality gradation complement results and land use change database, using spatial statistical analysis of ArcGIS, area-weighted average method, mean dichotomy method, and partial autocorrelation method, and as a basis for the zoning of cultivated land occupied by construction land. The agricultural acreage of Xiong'an New Area was 88 894.63 hm2. This research showed that the quality of cultivated land in the New Area was distributed from Grade 6 to Grade 14, and the average grade was 9.42, slightly higher than that in Hebei Province. Deviation value of cultivated land was from -3.42 to 4.58, with the lower dispersion in north and east part and higher dispersion in central and south part of the New Area. Cultivated land quality showed the high positive correlation in spatial distribution, LL type (Higher aggregation type) was distributed in the northeast and southwest, and HH type (lower aggregation type) was distributed in the northwestern, eastern and southern parts of the region. There was no obvious concentration area of HL and LH type (negative correlation type). Based on the results of local spatial autocorrelation, the occupancy rule of arable land by construction land was made, and the priority occupancy area, reserved occupancy area, maintained area of cultivated land, and river system regulation and control area were delimited, which were the recommended cultivated land occupied by construction land. The quality grade of cultivated land in the priority occupancy area was from 10 to 14, with the area of 40 981.03 hm2, occupying 26.4% of the total area, mainly distributed in the northern part of the New Area, closer to Rongcheng and Xiongzhou Town. The quality grade of cultivated land in the reserved occupancy area was from 9 to 11, with the area of 57 304.07 hm2, occupying 36.92% of the total area. The quality of cultivated land in the maintained area of cultivated land was from 6 to 9, with an area of 39 008.29 hm2, occupying 25.13% of the whole area, mainly distributed in the northeast and south of the New Area. The river system regulation and control areas were mainly distributed around the Baiyang Lake, occupying 11.55% of the total area. Through the rationality analysis, the recommended partition result is considered to be credible. Based on these results, the paper suggests that the low grade cultivated land should be occupied in priority, and the high grade cultivated land should be protected.
