The Research On Design Of Close-to-nature Forest Park

Since the beginning of this century, more and more sustainable development of forest resources has get people’s attention.Based on ecology, the "close-to-nature-forestry" is an effective method for forest resource sustainable development. The construction of Forest Park is getting into a stage of rapid development. On this condition,This paper use the method of AHP to construct a near-natureness value method.Via surveying the following4types of forest vegetation community:Coniferous forest, coniferous and broad-leaved mixed forest, broad-leaved forest and bamboo forest,get the Species diversity, stand vigor, structure characteristics,and disturbance degree.Adopt AHP Forest Park near nature degree evaluation system. Selection of tree species diversity, stand vigor, structure characteristics, the interference of12indexes in4aspects as the indicator layer, respectively:species richness, Pielou evenness index, Shannon-Wiener index, important value, top fitness, stand update, canopy density, volume, top species dominance, canopy structure, cutting intensity, snags condition; using gray correlation degree method, the constructed near nature degree of each index evaluation system to the dimension unity and quantization, completes to each index standardization; on4plots were near nature estimation, eventually get close to nature index of each sample was0.38,0.62,0.48and0.36.The forest naturalness is divided into I to VII in the7grade,4kind of close to nature is grade Ⅲ (native tree species plantations or exotic species and native species mixed forest), V (secondary), IV (native species mixed forest), Ⅲ (native tree species pure forest or exotic species and native species mixed forest). Shi Yanhu Forest Park forest near nature degree is low.Design the4diffrent improvement schemes.(1)The plant community of Shiyan lake near nature degree is low, the method of soil preparation and tending, create tending and mixed forest, which can quickly in a short time adorable shade forest, change the current state of degradation.(2)Forest community in medium near nature degree, as the scenic forest design, two aspects of tending shaping and tending transformation including the scenic forest, while taking into consideration the beauty of the forest.(3)The forest community high near nature degree, quasi as nature reserve special forest, methods in natural law management and closing combination.Near natural design of Forest Park was in ecology, the integrated use of forest cultivation Forest Park ecological technology to construction of near natural forest community. In this paper, Shiyan Lake Forest Park as an example for the shallow discussion, hope to provide valuable reference for the follow-up researches.
