黑河流域植被空间特征遥感分析及其分布特点形成机制

植被作为干旱区敏感的环境因子,能直观反映自然环境状况,任何植被覆盖变化都可揭示区域环境状况的演化与变迁。因此,植被覆盖变化研究已成为揭示干旱区自然环境变化及其规律的重要手段。文中通过2006年覆盖黑河流域的SPOT和TM影象数据的融合,制成具有丰富色彩和高分辨率的复合影象,建立植被判别标志对遥感影象解译进行分析从而得出黑河流域目前植被分布现状和特点,找出了植被分布特点的形成机制,为该流域的生态环境建设提出建议。

Vegetation space-characters and form-mechanism based on remote-sensing analysis in Heihe river basin

The vegetation,as the sensitive environment factor of the arid area,can reflect the natural environment condition immediately,and any change of the vegetation covering may indicate the evolution and the vicissitude in one region.Therefore,the research of vegetation covering change has the important means.In this artical the TM and spot phantom data of Heihe River Basin in 2006 were used to establish the symbol of distinguishing vegetation,and to analyze the remote sensing phantom.The forming system of vegetation distribution was discovered,and a suggestion about the ecological environment of Heihe River Basin was put forward.
