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.

Abstract

The invention relates to the technical field of data processing systems or methods specially suitable for administrative, commercial, financial, management, supervision or prediction purposes, and provides a cultivated land ecological sustainability evaluation method and system. The method is used for evaluating county-level cultivated land ecological sustainability in southern red soil hilly regions. The method comprises the following steps: according to a cultivated land ecological current situation of a research region, selecting indexes from four aspects of mine damage, landscape pattern, ecological stability, and ecological space occupation, and constructing a cultivated land ecological sustainability evaluation index system; combining subjective and objective factors, and combining an analytic hierarchy process and an entropy evaluation method based on a Lagrange multiplier method to determine index weights, wherein the cultivated land ecological sustainability evaluation index system comprises a plurality of cultivated land ecological influence factors, and each cultivated land ecological influence factor comprises a plurality of cultivated land ecological sustainability evaluation indexes; according to index values of the cultivated land ecological influence factors and a cultivated land ecological sustainability level, evaluating the cultivated land ecological sustainability.

Description

technical field [0001] This application relates to the technical field of data processing systems or methods specially applicable to administrative, commercial, financial, management, supervision or forecasting purposes, and in particular to a method and system for assessing 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 to the ecological restoration of land space and the promotion of sustainable agricultural development. 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...
