Abstract

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
