黑龙江省宝泉岭垦区耕地动态变化及集约利用评价

以宝泉岭垦区为研究单元,采用土地利用变化速率、土地利用程度综合指数等概念就数量和程度上分析1994-2008年耕地利用的动态变化过程,在此基础上,从投入强度、利用程度、产出效益、持续状况四个方面选取16个指标构建耕地集约利用评价体系,对研究区耕地集约利用程度进行定量分析及评价.研究结果表明:1.研究期内宝泉岭分局及各农...

The Arable Land Dynamic Analysis and Intensive Use Evaluation of Baoquanling Reclamation in Heilongjiang Province

Making Baoquanling Reclamatio as research object,using the concepts of land use changes in rates and land use degree composite index to analyze the dynamic change process of the arable land from land use volume and extent.The arable land intensive use evaluation indicators system of Baoquanling Reclamation includes 16 individuation indicators under 4 subsystems,such as input intensity,Utilization extent,production efficiency and continuous state.Adopting principal component analysis and Cluster Analysis to analyze and evaluate the objects.The results show that：1.During the research period,the arable land of Baoquanling Reclamation increased in quantity and arable land degree composite index showed an upward trend.The arable land was in adjustment except the year 2002 and 2003,other years in rapid development.2.From the perspective of intensive evaluation value of arable land,the diffreence of the level is distinguished,can be divided into hige,middle and low intensive use area.In following work,should adapt the method of land use management which is benefit to their development to different areas in order to improve the level of intensive use.
