- 摘要:
- 近年来土地利用驱动机制研究成为研究的热点，煤矿区是土地利用景观格局变化显著区域，该文主要研究土地利用景观格局动态变化及其调控原理。以2000-2010年遥感影像为基础，采用ERDAS软件对土地利用景观格局进行分类，研究景观格局的动态变化、转移矩阵及特征，结合七台河市煤矿区社会经济情况，确定影响景观格局因子的驱动力因素。结果表明：林草地、未利用地减少，耕地、矿业用地增加，动态变化度较大成为该时期土地利用景观格局动态变化的主要特征。第一产业总产值、人口数量是决定耕地的主要因子，林草地、矿业用地与第一、二产业产值及最终消费等经济驱动因素密切相关，同时市政府的环境保护及土地复垦、整治和恢复措施使矿业用地增长速度减慢。
- Abstract:
- The research on driving mechanism of land use change has been a hot spot, and the change of landscape types is obvious in coal mining area. This paper studied the dynamics of landscape types and regulation of the principle. Based on the remote sensing image of Qitaihe mining area from 2000 to 2010, the study area was classified by ERDAS. The changes were quantified by variation and converting matrix of the landscape types and characteristics. With the statistic data of society and economy in Qitaihe, this paper analyzed the driving force. The results showed that the area of forest-grass land and barren land were decreasing, the farmland and coal mining area were increasing, the variation of the landscape types was at a high level. Dynamics of landscape types was the main characteristic. Population and primary industry product were the main influencing factors for distribution of the change of farmland, and the forest-glass land and coal mining area were related with primary industry product and final consumption expenditure. Because of environment-protection policy and measures of land reclamation, remediation and restoration, the speed of coal mining land development increased slowly.
