摘　　要：土地利用结构优化不仅是数量的优化,更是空间优化,同时也是不同尺度的优化.本研究使用遥感技术(RS)获取土地利用的空间要素,提出了基于遥感和生态绿当量的优化卷积算法和优化模型,对区域内部非行政界线的多尺度数据进行土地利用结构优化.实例研究表明:该方法可实际应用于土地利用规划中,利用具有生态绿当量的的地类和RS来进行生态优化控制,实现任意区域与尺度的土地利用结构优化,提高土地利用总体规划的合理性和准确性.The optimization of land use structure is not only considered as the quantitative optimization, but also the optimization of spatial allocation and different scales. The spatial elements of land use were obtained by using the remote sensing technology. The optimization model and optimization convolution algorithm were proposed based on remote sensing and ecological green equivalent. Using these model and algorithm, the data of land use structure from multi-scales of every region which do not rely on the administrative boundaries were optimized. The result indicated that the method can be applied to optimize the land use structure. Based on the RS and the ecological green equivalent, the multi-scales land use structure optimization can be realized by dynamic control. The reasonability and accuracy can be improved in land use planning.
