基于Markov链的吉林西部土地利用结构优化研究
Land Use Structure Optimization Research Based on the Markov Chain in the West of Jilin Province
摘要
Abstract
Optimization of land use structure is the foundation and core of general land use planning. West of Jilin Province was taken as an example to optimize the land use structure research for the west of Jilin Province under the support of RS and GIS technology, using the Markov chain. The results showed that forest land, construction land, paddy field, dry land area would increase in land use of eastern Jilin by 2020, increase 153. 44, 227. 05, 1 479. 79, 80. 29 km2 , respectively; but grassland, water area, sand, saline and alkaline land, wetland had decrease, partly reduce to 1 569. 44, 493. 35, 60. 07, 1 029. 82, 389. 71 km2, respectively. The conclusion indicated that construction land expanded constantly, the area of grassland, wetland and water area reduced constantly, which was the main reason for a deteriorating ecological environment in the west Jilin Province. It was suggested to increase appropriately grass and forest land scale, to protect wetland and water area reasonably, limit construction land expansion blindly, tap the stock of land for construction purposes, to improve the utilization rate of construction land in order to realize sustainable utilization of land resource in the future.关键词
