摘要
耕地质量提升可分别从地块尺度与项目尺度进行时序安排研究,对于了解县域耕地质量高低及其分布情况、合理布设提升建设项目具有重大意义。以河北省卢龙县为研究区,在农用地分等影响因子的基础上补充通过耕地整治工程可改善的耕地质量影响因子,构建耕地质量提升时序评价指标体系。运用逼近理想点法求得耕地质量提升地块尺度的时序,并用贴近度作为提升地块尺度时序安排的度量;并对地块尺度时序中的耕地图斑进行距离分析,得到耕地质量提升建设项目的时序。结果表明:卢龙县耕地质量优先提升区耕地总面积为13 501.16hm^2,次优先提升区耕地总面积为13 131.85hm^2,后优先提升区的耕地总面积为14 093.62hm^2。结合卢龙县实际得出可布设耕地质量提升建设项目的面积情况为:优先提升区共10 839.45hm^2,安排6个建设项目;次优先提升区共3 824.31hm^2,安排4个建设项目;后优先提升区共8 726.37hm^2,安排7个建设项目。该研究可为开展具有区域特色和务实高效的耕地质量提升的建设工作提供科学参考。
With respect to the improvement in cultivated land quality,study on scheduling research respectively on the parcels scale and the project scale is of great significance to understand the cultivated land quality in a county,its distribution and layout of the construction projects,and promotion of the construction project.Based on Lulong County in Hebei Province as the research area,this study adds impact factors of cultivated land quality which can be improved by land consolidation engineering on the basis of the impact factors of farmland classification,construction evaluation index system of improvement sequence of cultivated land quality.We get the parcels scale sequence of land quality improvement by using method of approximating the ideal point,uses the close degree as measurement of improvement of the parcels scale scheduling,the distance analysis of cultivated land in land scale sequence,and get sequence of construction projects for improving the quality of cultivated land.The result shows that the area of the preferential improvement zone of cultivated land quality in Lulong County is 13 501.16hm^2,the area of the second preferential improvement zone is 13 131.85hm^2 and the area of the last preferential improvement zone is 14 093.62hm^2.With respect to the reality of Lulong County,the area of cultivated land quality improvement project is as follows.The area of preferential promotion zone is totally 10 839.45hm^2,6construction projects were arranged in this area;the second preferential improvement zone has a total area of 3 824.31hm^2,and 4construction projects wre arranged in this area;the last preferential promotion zone has a total area of 8 726.37hm^2,7constructionprojects were arranged in this zone.These results can provide references for carrying out the pragmatic and efficient construction work of the improvement in cultivated land quality with distinctive regional features.
