摘要:

耕地酸化治理是提升耕地质量和保障粮食安全的重要举措,本文以广东省为例,系统分析广东省耕地土壤酸化现状、时空演变特征及治理状况,采用实地调研、层次分析、专家咨询等方法,得出广东省耕地酸化治理存在标准支撑不足、治理模式单一、政策衔接不够、管护资金不足等困境,总结提出基于标准化建设、模式探索、政策激励和公众参与的耕地土壤酸化治理路径,并提出了加快制定标准规范、开展模式探索、强化政策衔接、建立后期管护长效机制等相关建议,旨在为耕地酸化治理助推粮食安全提供参考。

Abstract:

The management of soil acidification of cultivated land is an important measure to improve farmland quality and ensure food security. Taking Guangdong Province as an example, this paper systematically analyzed the current situation, temporal and spatial evolution characteristics and management modes of soil acidification of cultivated land in Guangdong Province. By using the methods of field investigation, analytic hierarchy process and expert consultation, the study concludes that there are some difficulties in the management of soil acidification of cultivated land in Guangdong, such as insufficient standards, management modes, policy cohesion and funds. The study puts forward suggestions on building management path of soil acidification of cultivated land in Guangdong based on developing standards and specifications, model exploration, policy incentive, public participation and the establishment of long-term mechanism, in order to ensure food security.

Key words: cultivated land, soil acidification, management, path, suggestions
