| 摘 要： | 针对辽西北中轻度沙化土地的区域特点和特殊性,通过分析其沙化土地的光谱特征、空间分布及时间变迁特征,研究了一种时空约束下的多光谱遥感影像沙化土地识别方法。在对沙化土地进行光谱特征分析的基础上,加入时-空分布特征进行约束修正,有效提高了沙化土地监测的精度和效率。

| Abstract: | According to the characteristics of the mild desertification land in the Liaoning northwest , through analysis of the spectral characteristics , spatial distribution , and time change features of desertification land .A desertification land recognition method by u-sing multi-spectrum remote sensing image and spatio -temporal constraint was studied .Based on the analysis of spectrum character-istics of the desertification land , spatio-temporal constraint correction was involved .This method effectively improves the accuracy and efficiency of land desertification monitoring . |
