Abstract

Abstract: Land resources are the material basis for people's survival and development. Land irrigation environment is an important content of land resources surveys, and the spatial configuration of key infrastructure motorized wells has important practical significance for agricultural production. This paper takes Yongledian, Tongzhou, Beijing as the research area, and based on the multi-source spatial data of the land and resources survey, proposes a method for quantitative evaluation and optimization decision-making of the existing land irrigation environment. The results show that the configuration of existing organic wells in the study area needs further improvement. The 183 updated motorized wells given by the optimization plan are reasonably allocated in the set units, which can meet the land irrigation needs of local farmers and provide for the updated configuration of motorized wells in the land irrigation environment.

Key words: land irrigation environment, motorized well, simulated annealing algorithm, decision analysis, land resources
