At large scale, the result of comparing of optimization structure of forest type with the present structure of forest type illustrates that the present economical forest area is larger while the mixed forest is smaller. So decreasing economical forest area and increasing mixed forest area should be the main measurements to optimize spatial patterns. At small scale, the evaluation of the landscape inner structure index illustrates that the forest structure and coverage is smaller, which should be regulated and so the uneven-aged, multi-layered and mixed forest should be the object of the forest structure design.

大尺度上根据植被类型优化结构和现有植被类型结构数据的对比分析可知，现有经济林面积则过大，混交林面积较小，因此主要是减少经济林面积，改造针叶和阔叶纯林为混交林，从而增加混交林面积，以达到最优植被类型结构时的空间配置；在小尺度上通过对景观内部结构指数的计算分析可知，该区林分结构和郁闭度分指数值较小，应予以着力调整；由研究结果可知，异龄、多层次、混交的水源保护功能最好，因此稳定的林分结构设计目标就是尽量使林分形成异龄、多层次、混交林。
