A method and system for evaluating the ecological sustainability of cultivated land

Abstract

The present application relates to the technical field of data processing systems or methods specially suitable for administrative, commercial, financial, management, supervision or forecasting purposes, and provides a method and system for evaluating the ecological sustainability of cultivated land, which is used for evaluating the county-level scale of the southern red soil hilly region. The method includes: selecting indicators from four aspects of mine damage, landscape pattern, ecological stability and ecological space occupation according to the current ecological status of cultivated land in the study area, and constructing an evaluation index system for ecological sustainability of cultivated land ; Combining subjective and objective factors, and combining AHP and entropy value method based on Lagrange multiplier method to determine the index weight; wherein, the evaluation index system of cultivated land ecological sustainability includes a plurality of cultivated land ecological impact factors; The cultivated land ecological impact factor includes a number of cultivated land ecological sustainability evaluation indicators; according to the index value of the cultivated land ecological impact factor and the cultivated land ecological sustainability level, the cultivated land ecological sustainability is evaluated.

Description

technical field [0001] The present application relates to the technical field of data processing systems or methods specially suitable for administrative, commercial, financial, management, monitoring or forecasting purposes, and in particular to a method and system for evaluating the ecological sustainability of cultivated land. Background technique [0002] As an important part of agricultural space in land space planning, cultivated land protection is of great significance for ecological restoration of land space and promoting sustainable agricultural development. In order to increase grain output and develop the economy, under the extensive production mode, due to the influence of climate change and unreasonable human use, some cultivated land is facing increasing ecological pressure, which seriously restricts the sustainable development of agriculture.

Problems solved by technology

In order to increase food production and develop the economy, under the extensive production mode, affected by climate change and unreasonable human use, some cultivated land is facing increasing ecological pressure, which seriously restricts the sustainable development of agriculture.

[0003] Since the 1980s, the ecological restoration of land space has mostly started from the three major spaces of ecology, agriculture, and towns, and coordinated and scientifically carried out the integrated protection and restoration of mountains, rivers, forests, fields, lakes and grasslands. However, there is a lack of detailed research on the ecological restoration of different land use types in various spaces.

On the other hand, for a long time, ecological restoration has paid more attention to the ecological restoration technology research of ecological space, while the research on ecological restoration technology of agricultural space is insufficient. To comprehensively evaluate the ecological sustainability of county-level cultivated land development, there is no systematic evaluation framework at present, which is not conducive to the improvement of agricultural productivity and the sustainable development of agricultural space

[0004] The research objects of existing sustainable evaluation methods mostly focus on economic and social factors such as productivity, intensification, and driving forces, such as pressure-state-response type, niche theory, emergy analysis, etc., and seldom focus on natural environment factors. It is difficult to comprehensively analyze the ecological sustainability evaluation indicators in the process of index construction, and it is unable to reflect the spatial differences of the county-level cultivated land ecological sustainability evaluation results, which is not conducive to the development of local conditions.
