京承高速沿线土地利用季相变化遥感监测及其景观格局分析

为了科学准确地获取京承高速沿线土地利用变化情况,并分析相关建设对沿线生态景观格局的影响,本文选择2006年冬季-2008年夏季间多时相遥感数据和专题数据,进行专题知识引导下的土地利用季相变化检测与信息提取,并结合实地调查数据获得了四个季相的土地利用现状数据。经对其进行土地利用变化及景观格局定量分析,结果表明:由于大力加强现代农业走廊建设,农业用地增加1.06%,裸露农田及废弃地减少6.16%,休闲用地增加1.59%,沿线景观格局得到了优化,并对改善和治理季节性裸露农田、废弃地等起到了示范作用,为都市农业走廊规划与效果评价提供决策依据。

Monitoring land use seasonal changes and analysis of landscape patterns along JingCheng highway based on remote sensing

In order to obtain the land use changes along Jingcheng highway,and to analyze the results of the ecological landscape patterns for related modern agriculture projects,in this paper,the multi-temporal remote sensing data from winter in 2006 to summer in 2008 and land use thematic data were selected to perform an automatic seasonal changes detection and information extraction guided with land use parcels knowledge.All detected changes were tested with in-situ investigation.From the quantitative analysis of land use change and landscape patterns,the result showed that,due to strengthen building the modern agricultural corridor,the landscape patterns were optimized,which has played an important role for the improvement of seasonal bare cropland and wasteland.
