摘要
Zhenlai county in Jilin Province is taken as a typical area to explore the universal land use pattern under ecological security in ecotone between agriculture and animal husbandry in Northeastern China. Remote sensing data, relative thematic maps and corresponding social-economical statisitical and planning data were collected, and grey linear programming (GLP) model, together with the synthetic index estimating method was applied to develop an optimal land use model to evaluate the ecological security and analyze decision. The land use structure and optimal spatial allocation pattern of Zhenlai county in the year of 2010 regarded as a land use pattern under ecological security were simulated out by the mathematical models applied.
