鉴于传统人工调查生态环境时人力、物力投入较大,且不利于宏观大范围的观测。文中利用选取赣江源地区的石城县为研究区,以Landsat卫星的TM影像为数据源,利用遥感技术提取关键的生态因子,并将植被覆盖度、土壤指数、坡度等信息进行归一化,建立生态环境评价模型。运用该模型对赣江源地区近20年的生态环境质量进行动态监测。结果表明:赣江源地区的总体自然生态环境良好,其东北部和东南部及西部的自然生态环境好于中部地区,生态环境整体不断改善。采用遥感方法进行赣江源生态环境综合评价是可行的。
鑒于傳統人工調查生態環境時人力、物力投入較大,且不利于宏觀大範圍的觀測。文中利用選取贛江源地區的石城縣為研究區,以Landsat衛星的TM影像為數據源,利用遙感技術提取關鍵的生態因子,併將植被覆蓋度、土壤指數、坡度等信息進行歸一化,建立生態環境評價模型。運用該模型對贛江源地區近20年的生態環境質量進行動態鑑測。結果錶明:贛江源地區的總體自然生態環境良好,其東北部和東南部及西部的自然生態環境好于中部地區,生態環境整體不斷改善。採用遙感方法進行贛江源生態環境綜閤評價是可行的。

Given that the traditional artificial ecological investigation needs larger human power and material resources, and is not conducive to a wide range of macro-observation, the article selects Shicheng county in Ganjiang source region as research area, with data source of TM image from Landsat satellite, using remote sensing technology to extract the key ecological factors, normalizing the vegetation coverage, soil index, slope information to build an assessment of the ecological environment model. Using the model for dynamic monitoring of the ecological environment quality in Ganjiang source region in the nearly 20 years, the result shows that the overall natural ecological environment in Ganjiang source region is fine, the natural ecological environment in the northeast, southeast and the west are better than that of the central region, and the overall ecological environment is improving. In the whole, using remote sensing method for ecological environment comprehensive evaluation of Ganjiang source region is feasible.
