Abstract


The forest aesthetic theory and applied research is focused on the development direction of the current forest managers disciplines. As one of scenic forest landscape aesthetic evaluation of scenic forest landscape planning and design work, the fundamental task is how to create a set of index system of scenic forest landscape aesthetics play function rational evaluation, reveals the existing scenic forest landscape aesthetics problems and determine the direction of future development, to provide the basis for the scenic forest landscape planning and design. Therefore, the study of scenic forest landscape aesthetic evaluation to promote the development of the scenic tourism has important theoretical and practical significance. Constructed the evaluation index system of scenic forest landscape aesthetics. Screened by summarizing the research at home and abroad, the five areas 16 Evaluation Evaluation of scenic forest landscape aesthetics, natural forest area ratio, anthropogenic interference with the degree of seasonal changes, geographic conditions, exotic species, scientific and historical value, typical degrees relative abundance of landscape types, diverse topography, structural complexity, species diversity, deep, openness, level of constitutive King, the internal environment of the coordination and the external environment, coordination, etc.. To landscape aesthetics index concept. Calculation of the score value of the 16 indicators of the evaluation system of scenic forest landscape aesthetics and weight of the product of the accumulated value is defined as landscape aesthetics index. According to the the landscape aesthetics index size measured by the beautiful landscape of scenic forest. Try the screening of the rough set theory is applied to the evaluation of scenic forest landscape aesthetics, a decision attribute without constructing rough set evaluation method based algorithm to distinguish between the matrix and logic operations applied to the evaluation set of scenic forest landscape aesthetics optimization process. The one hand, the use of rough set attribute reduction ideology, delete redundant indicators, streamline and optimize the evaluation index system of scenic forest landscape aesthetics; the other hand, attribute importance in rough set theory thinking, determine the index weight, to overcome subjective evaluation method relies priori knowledge support research field defects. Such an evaluation based on rough set theory proposed by both the integrated evaluation of scenic forest landscape aesthetics, both to optimize the index system, but also to increase the objectivity of the evaluation process. Longshan Forest Park case empirical analysis of scenic forest landscape aesthetic evaluation based on rough set computing, come to the park five scenic landscape aesthetics index Yao Wang scenic 6.657, the iron lion Ping scenic 6.629, flying water Ya the scenic 5.868, tea bamboo scenic 5.783 Baimahu scenic 4.216. Each scenic scenic forest landscape transformation suggested.
