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。
In order to obtain scientific and accurate land use change along Jingcheng Expressway and analyze the impact of related construction on the ecological landscape pattern along the route, this paper selects the multi-temporal remote sensing data and thematic data from 2006 to summer 2008, Land use seasonal change detection and information extraction, and combined with field survey data obtained four seasonal phase of land use status data. The results showed that agricultural land increased by 1.06%, bare land and wasteland decreased by 6.16% and recreational land increased by 1.59%, and the landscape pattern along the route was obtained as a result of the land use change and landscape pattern quantitative analysis. Optimize, and play an exemplary role to improve and control seasonal exposed farmland, abandoned land, etc., to provide decision-making basis for the planning and effect evaluation of urban agriculture corridor.
