Regional land utilization optimization configuration method

Abstract

The invention discloses a regional land utilization optimal configuration method. The method specifically comprises the following three steps: predicting the optimal numerical values of various land utilization areas; secondly, preliminarily spatializing numerical values of land utilization configuration; and finally, carrying out ecological verification and image feedback adjustment according tohistorical data until a design year land utilization optimal configuration diagram which simultaneously meets the water-reducing and sand-reducing effects in the ecological requirements is obtained. Prediction conditions of the method are based on policies and current situation data; a operation research linear programming algorithm is used, so that each prediction result meets the numerical rangeof each index of the planned level year; the land configuration change and the water and sand change caused by the land configuration change can be systematically analyzed and discussed; a coupling relation is formed among a land configuration mode, economic benefits, landscape indexes and runoff sediment, a system can be flexibly adjusted for optimization, and the land configuration prediction method is high in reliability, interpretation degree and freedom degree and gives consideration to economic development and ecological protection.

Description

technical field [0001] The invention relates to a linear optimization design combined with operations research in the fields of landscape ecology and hydrology, and is a method for predicting and regulating land use allocation based on economic development while taking ecological environment into consideration. Background technique [0002] Soil and water loss has become one of the most serious environmental problems in China. A large amount of soil and water loss has caused the degradation of the regional ecological environment and severe damage to economic development; in the fields of landscape ecology and hydrology, many related natural science laws have been discovered and demonstrated, such as regional The coupling relationship between land use configuration and runoff, sediment, the coupling relationship between land use configuration and economic development, etc., but so far, many natural coupling relationships and geospatial technologies with excellent fitting degre...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for optimal allocation of regional land use, which solves the problem that the existing method cannot freely add various policy requirements that have been quantified. It is only a pure mathematical model, and its prediction results change randomly and cannot be explained reasonably Problems with low reference value for actual regional planning
