Landscape estimation and management technique principles of different seasonal scenic and recreational forests in West Mountain,Beijing

In order to manage the different seasonal scenic and recreational forests in West Mountain of Beijing scientifically, the landscapes of main forest vegetations in spring, summer and autumn were estimated by scenic beauty estimation (SBE) method. The multivariate regression models for estimation and forecast between favor degrees and different landscape factors were established by Quantitative Theory I. The management technique principles of different seasonal scenic and recreational forests were analyzed. The results show that the seasonal landscapes of scenic and recreational forests are abundant and the management technique principles can highly improve the landscape level of scenic and recreational forests in this area.
