The Research On Evaluating The Scenic Forest Landscape Aesthetic Based On Rough Set

Forest aesthetic theory and application of the current forest management disciplines is the focus of the direction of development. Scenic forest landscape aesthetics evaluate as a planning and designing work of the foundation. To establish a set of indicators on the system played by the scenic forest landscape aesthetics functions reasonable evaluation is the fundamental task. Scenic forest landscape aesthetics is revealed the existing problems and the determining the direction of future development for the scenic forest landscape providing a basis for planning and designing. Under this background, these was great theoretical and practical significance which researched scenic forest landscape aesthetics evaluation for promoting tourism development in scenic areas.Scenic forest landscape aesthetic evaluation index system is constructed. Through the evaluation of the scenic forest landscape aesthetics is selected on th five aspects of 16 evaluation indexes, that is the natural forest area ratio, the level of human disturbance,seasonal changes, geographic conditions, exotic species, research and historical value, typical degrees, the relatively abundant of landscape types, diversity of digital and morphological, complexity of the structure, species diversity, remote and quiet, open, conformation king level, the internal coordination and external environment and the environment and so on.Landscape Aesthetics'index is put forward the new concept. According to scenic forest landscape aesthetics evaluation indicators measuring, the scenic forest of each indicator producting its weight, and cumulativing their value defined as the landscape aesthetics'index. The level of the beautiful scenic forest landscape is measured to the size of the landscape aesthetics'index.Attempting to rough set theory applied scenic forest landscape aesthetic evaluation. The need to construct a rough set attributes of the decision-making evaluation, based on the distinction between the discernibility matrix and logical algorithm will be applied to set screening optimization process of the scenic forest landscape aesthetic evaluation index.On the one hand, using rough sets attribute reduction ideas, deleting redundant indicators, streamline and improve the evaluation index system of the scenic forest landscape aesthetics. On the other hand, using the important attributes of thinking of the rough sets theory, weighting indicators, overcoming the subjective evaluation methods depend on the support of a priori knowledge deficiencies in the research areas. Based on the rough set theory of this evaluation, we optimize the index system and increase the objectivity of the evaluation process through comprehensive in the scenic forest landscape aesthetic evaluation.In case the forest park of Longshan for the empirical analysis, the scenic forest landscape aesthetic evaluation operator based on a rough set, and obtain the five scenic spots landscape aesthetics index in the park, which are the scenic spots of Yaowang 6.657, the scenic spots of Tieshi Ping 6.629, the scenic spots of Feishui cliff 5.868, the scenic spots of Chazhu lake 5.783, the scenic spots of White Horse Lake 4.216. Each scenic spots of the scenic forest landscape transformation made some recommendations.
