Evaluation of the comprehensive potential for land reclamation in Huadian City

[摘要] In order to understand the potential for land reclamation in Huadian City, this research constructs an evaluation model for land reclamation potential based on the double restraints of ecological security and social economy to measure comprehensive potential for land reclamation that conforms to the level of regional development and ecologic protection objective. The research shows: (1) Under constraint conditions, the potential for land reclamation in the towns of Huadian City has been reduced in different degrees, with the change of potential in urban areas being much smaller than in rural area. Under the restraint of ecological protection, Jiapigou Town, Erdaodianzi Town, Hongshilazi Town and Changshan Town suffer the high restraint. In terms of restraint of social economy, Huashulinzi Town is subject to the high constraint. (2) During the 13thFive-Year Plan Period, through arable land reclamation, Huadian City will have 4,121.47 more hectares of arable land and save 2,410.82 hectares of construction land. The findings provide an approach to land reclamation potential evaluation and form a basis for the compiling of the plan for land reclamation during the 13thFive-Year Plan Period.
