Abstract:

The evaluation of main types of in-forest landscapes in the mountain area of west Beijing was conducted,44 representative photoes of in-forest landscapes and interrelated material were collected.The Public Judgment Method was adopted in acquiring the likeliness values to every in-forest landscape.Then the empirical model between likeliness values and 15 constituting elements was established by using Polybasic Mathematical Theory Ⅰ. The model showed that,the main factors which effect the quality of in-forest landscapes most efficiently were:form of trunks,dead trees & fallen woods,arrangement of trunks,coverage of ground plants,uniformity of ground plants,degree of slope.Besides,the method of field work,the decomposition of in-forest landscape elements,the general characteristics of judged landscapes,procedure of landscape judgment were stated in detail,and the conclusion of evaluation was also analyzed.

Key words: In-forest landscape, Evaluation, Landscape judgment, Landscape element, Model
