High Standard Farmland In Xinshao County Based On Land Ecological Security Construction Path Study

High standard farmland construction,protection and development is a material basis for ensuring our food security and an important guarantee to improve our comprehensive agricultural benefit,which has an important strategic significance and far-reaching practical influence on our future agricultural development.However,high standard farmland construction is mainly focused on the improvement of farmland production function and less consideration of farmland ecological environment protection,which is not conducive to the development of Chinese agriculture in the direction of ecological friendliness and sustainable resources.Therefore,from the perspective of land ecological security,this paper evaluates the land ecological security in the construction of high-standard farmland,and provides an optimization path that helps to strengthen the construction of land ecological security.The purpose is to strengthen the protection and utilization of land resources and promote the sustainable development of agriculture on the basis of meeting the high standard of farmland stable and increasing production.This paper takes Xinshao County as the research area,based on the general system theory,man-land coordination theory and sustainable development theory,and on the basis of summarizing the research results of domestic and foreign scholars,constructs the land ecological security evaluation system of high-standard farmland construction.The evaluation indexes of Xinshao County from 2019 to 2021 are selected from three aspects: pressure,state and response.In terms of weight assignment,AHP and entropy weight method are combined for comprehensive weight assignment.In the evaluation method,the matter-element evaluation method is used to calculate the comprehensive correlation degree between each index and criterion layer,so as to determine the evaluation level of land ecological security in the construction of high standard farmland.The results showed that the land ecological security of high standard farmland construction in Xinshao County from 2019 to 2021 was generally at a relatively safe level.However,there are still inefficient factors affecting the construction of land ecological security,such as the lack of protection of biodiversity,the improvement effect of cultivated land quality level is not significant,the problem of pollution has not been fundamentally solved,the construction standard per mu is low and the soil improvement fund is insufficient,and so on.In order to promote the construction of high-standard farmland ecological security,we should strengthen the construction of farmland ecological facilities,improve the quality level of cultivated land,establish a long-term mechanism for pollution control,and strengthen the investment and introduction of social capital.
