Method for determining comprehensive reclamation utilization direction of coal mine temporary construction land

Abstract

The invention discloses a method for determining a comprehensive reclamation utilization direction of a coal mine temporary construction land. The method comprises the following steps: taking a coal mine temporary construction map spot generated by using an inflection point coordinate of a to-be-reclaimed coal mine temporary construction land range as an evaluation unit; determining reclamation indexes of the evaluation unit in different reclamation directions according to reclamation factors including natural factors, location factors and environmental factors; calculating comprehensive ecological suitability indexes of the evaluation unit in different reclamation directions according to the determined reclamation indexes of the evaluation unit in different reclamation directions; and determining the comprehensive reclamation utilization direction according to the calculated comprehensive ecological suitability indexes of the evaluation unit in different reclamation directions. According to the method, visual description can be carried out in the reclamation utilization direction of the agricultural land, the reclamation utilization direction of a construction user and the reclamation utilization direction of the ecological land, and the advantages in the change trend can be analyzed, so that scientific reference and basis are provided for making a reclamation utilization decision of the temporary construction land of the coal mine.

Description

technical field [0001] The invention relates to ecological reclamation and utilization of land for temporary construction of coal mines, in particular to a method for determining the direction of comprehensive reclamation and utilization of land for temporary construction of coal mines. Background technique [0002] Cutting overcapacity and adjusting structure are important means to promote economic leap-forward development and an effective way to strengthen the construction of ecological civilization. Since the implementation of the coal industry's capacity reduction policy, my country has closed a large number of mines with backward production capacity and integrated a large number of small and medium-sized mines. In 2016 alone, about 2,000 coal mines were closed and withdrawn. While promoting economic development and the construction of ecological civilization, Guantui Coal Mine has also abandoned a large amount of temporary construction land. How to realize the ecologica...

Problems solved by technology

Due to the characteristics of remote location, scattered distribution, and forced occupation of temporary construction land for coal mines, in the current reclamation and utilization, too much emphasis is placed on the agricultural use of temporary construction land or reclamation according to the original appearance before occupation, and some temporary construction land will face poor ecological benefits, High economic cost, low public satisfaction and many other problems

In recent years, researches in the field of land reclamation and utilization have mostly focused on the destruction of land by permanent land use such as industrial and mining wasteland and residential areas, and the destruction of land by construction projects such as energy, transportation, and water conservancy projects. ] , but there is a lack of research on reclamation and utilization of temporary coal mine construction land; in terms of research methods, Delphi method is mostly used ] , Analytical Hierarchy Process, Exponential Sum Method, Limit Condition Method [7] and fuzzy comprehensive evaluation method [8] etc. There is a lack of comprehensive evaluation of the data system; in the direction of reclamation and utilization, farmland reclamation is the main direction, and there is no comprehensive reclamation direction to create a life community of "mountains, rivers, forests, fields, lakes and cities" and coordinate the three-life space
