Land utilization benefit evaluation method and system

Abstract

The invention discloses a land utilization benefit evaluation method and system, and belongs to the field of land resource management and urban planning, and the method comprises the steps: summarizing the land idle time cost of unavailable land and idle land in a to-be-evaluated region, and obtaining the value loss caused by the idle land of the to-be-evaluated region, namely the land utilization social cost; the land utilization economic output of the to-be-evaluated area is obtained by counting the GDP of the constructed land of the to-be-evaluated area in the evaluation time period; the land utilization ecological output of the to-be-evaluated area is obtained by quantifying the park green land ecological service value of the constructed land of the to-be-evaluated area; according to the method, the income or cost of land utilization is quantified from the three aspects of society, economy and ecology, the unit area land net output of the to-be-evaluated area is obtained after integration, then the land utilization benefits are evaluated, the method is simple in calculation, data are easy to obtain, and the land utilization benefits can be evaluated simply and efficiently.

Description

technical field [0001] The invention belongs to the fields of land resource management and urban planning, and more specifically relates to a land use benefit evaluation method and system. Background technique [0002] Land is the bearing space for all social and economic activities. In recent years, the blind expansion of rapid economic growth at the cost of extensive and inefficient use of land has resulted in serious waste of land resources and irrational land spatial layout. The essence of land use benefit is the material output or beneficial results realized by unit area land input and consumption in the social, economic and ecological aspects of regional development. [0003] The existing evaluation objects of land use efficiency mainly evaluate the built-up land in urban built-up areas, and there are few quantitative evaluation studies on idle land and approved but unused land. At the same time, most of the existing studies evaluate from the perspective of input and ...
