【摘要】：耕地后备资源需在区域不同的资源条件与利用方向基础上,进行针对性的差异化保护与开发管理,以发挥资金投入的最佳效益,实现开发区域的协调发展。以黑龙江省为研究区,综合考虑耕地后备资源集聚条件、资源投入意愿和资源开发潜力,运用空间分析和两维图论算法进行县域尺度下耕地后备资源利用分区,确定不同的调控方向。分区结果表明:两维图论聚类法较好实现了耕地后备资源利用分区之间的独立性及分区内部一致性;将黑龙江省分为潜力开发、生态环境建设、重点开发、生态环境保护、开发利用管控和适度开发6个耕地后备资源利用类型区,针对不同利用类型实施差别化的保护与开发管理战略。
[Abstract]:On the basis of different regional resource conditions and utilization directions, cultivated land reserve resources should be protected and managed in order to bring into play the best benefit of capital investment and to realize the coordinated development of the development area. Taking Heilongjiang Province as the research area, considering the conditions of cultivated land reserve resource accumulation, resource investment willingness and resource development potential, spatial analysis and two-dimensional graph theory algorithm are used to partition the utilization of cultivated land reserve resources at county scale. Determine different control directions. The results show that the two-dimension graph theory clustering method can realize the independence and internal consistency of the arable land reserve resources utilization zones, and divide Heilongjiang Province into potential development, ecological environment construction, key development, ecological environment protection, and so on. Development and utilization control and appropriate exploitation of 6 types of arable land reserve resources, the implementation of different utilization types of protection and development management strategy.
