摘要:
从MODIS数据中提取反映福建省植被生态环境的植被、湿度、热度、土壤亮度等遥感指数,与在GIS环境下生成的地形数据(高程和坡度)及趋势面拟和形成的气象数据进行复合,生成综合评价影像(共17层),按一定的数学方法对评价指标进行处理与筛选,确定最后的参评指标,通过多元线性回归方法确定各指标的权重,建立福建省植被生态环境遥感本底值模型,并利用该模型对福建省植被生态环境进行评价.
Abstract:
RS indexes such as vegetation,humidity,heat and soil lightness,which reflect the vegetation eco-environment of Fujian,are abstracted from MODIS data.They are integrated with terrain data(of altitude and gradient) generated on the basis of GIS and meteorologic data developed in way of trend-surface fitting,with overall evaluation images(in 17 layers) formed as the outcome.The evaluation indexes are handled and selected through mathematic approaches.After the final evaluation indexes are decided,the proportion of each index is identified through multi-factors linear regression.At last,RS background value-based on model of Fujian’s vegetation eco-environment is established,and is used to evaluate the vegetation eco-environment of Fujian.
