| 摘 要： | 利用冬夏2个不同时相的CBERS—02卫星数据与实地调查资料，采用主成分分析与监督分类相结合的方法，提取浙江临安市的山核桃空间分布及种植面积信息。结果表明：山核桃面积提取总体精度达到83．71％，面积为3．11万hm2，与统计数据相比误差为1．3％；利用山核桃冬夏2季在图像上的差异特征，采用遥感变化监测方法提取山核桃种植面积是可行的。

| Abstract: | Based field survey data, the on the CBERS -02 data collected in the summer and winter seasons being integrated with spatial distribution and area information of Carya cathayensis in Lin＇an Municipality, Zhe- jiang Province were extracted by means of the Principal Component Analysis （PCA） combined with supervised clas- sification methods. It was showed that the total area of C. cathayensis plantation area in Lin＇an was 3.11 million hm2, the overall extraction precision was 83.71%. Compared with statistical data, the precision error was 1.3%. The results showed that extracting C. cathayensis plantation area information was feasible by remote sensing-based dynamic monitoring with the characteristic differences between the winter and summer images. |
