| 摘 要： | 本文从非耕地系数的计算公式和遥感数据对地理要素的综合着手,研究在多尺度下非耕地系数的变化特征.研究结果表明:大尺度数据下的非耕地系数比中、小尺度数据下的要大；建立了TM和中巴数据尺度下的非耕地系数之间的数学模型,该模型使得非耕地系数在此两种尺度数据下可以相互转换.通过模型检验,线性模型符合精度要求.

| Abstract: | Non-cultivated land in cultivated land is the key factor effecting monitoring cultivated land area using Remote Sensing technology on a large scale.In this paper,the conception of non-cultivated land coefficient was proposed to express the percentage of non-cultivated land in arable land.Non-cultivated land coefficient shows the effects of human activities to the cultivated land.The results were as follows:theoretically,non-cultivated land coefficient was increasing from down-scale to up-scale.In this paper,the model between non-cultivated land coefficients under different scales was built.The model in the paper could express the exchanges of non-cultivated land coefficients under different scales.The paper discussed the non-cultivated land coefficients under the usually used data scale.The linear model,which could meet the requirements of precision,was useful in exchanging the non-cultivated land coefficients between TM and the CBERS data scale. |
