【摘要】 本文利用博爱县国有林场部分遥感TM卫星图片和相关资料建立了目视解译标志,根据所建立的解译标志对地物进行遥感判读,在室内勾绘出各地类边界,用聚酯膜法对面积进行判读。同时为了提高判读精度,得出更加真实可靠的资料,本文利用从现地调查的90个小班的面积和相应的图上判读面积,建立线性模型.然后对建立的模型做显著性检验及x2适合性检验,结果表明用所建立的线性回归模型算出的地类面积与现地调查的面积基本相符,无显著差异。更多还原

【Abstract】 This paper carried on the visual solution using the some remote RS TM chart of state forest farm of bo’ai county to establish the translation symbol, according to the solution which have established symbol to the place thing, we carried on interprets, and draw each place’s boundary in the room, then extract the area with the polyester membrane method. In order to improve the interprets precision and to obtain a more real reliable material, The linear models were establish using 90 sub-compartments’ area which investigated from the location and the corresponding map reading area, Then linear relation of the models were proved very notable by notable test. The x2 tests show that the difference of the two areas from the result of location survey and the result of the corresponding model is not notable.更多还原
