| The main vegetation is of ever-green seasonal broad-leaf forest in area of Guangzhou, including some association such as communities of Castanopsis fissa,Syzygium hancei and Machilus chinensis,etc.The flowering Castanopsis fissa is very important forest landscape in Guangzhou as well as Pearl River Delta from spring onto early summer. According to the conception and research method of forest aesthetic and forest landscape, within color evaluation and AHP analysis, the community of Castanopsis fissa is studied in an attempt to describing the correlation between forest landscape with tree species composition. The results shows as follow:(1) The color of plants is most rich and impressional in spring but the longer green landscape is not fit for the color in the plant configuration, so it should pay attention to the the blossom tree and leaf-color changes between the spring and summer. To arrive the rich landscape and colorful change in southern China, the proposed designer should focus on the seasons change for a theme in plants to choice with one or two main species to arrive the different landscape effects.(2) Sampling landscape fissa in fissa main forest community, Sapium discolor, neem leaf Evodia, trickle draft, superba, cattle wood, red gum and other components, the specific composition of different locations slightly different tree species. The Castanopsis fissa community have10～20meters in average height, but the community will be decrease the kinds of the Castanopsis fissa plants and add the height superior to20meters in forest after the the community have degraded. Upper tree species as fissa, neem leaf Evodia, Sapium discolor, understory layer cattle wood, jackals skin Zhang, silver wood, etc., herb layer Dicranopteris linearis, fan maidenhair fern, creeping bamboo atrazine, rags, leaves, nine, Smilax, leaflets, etc. to buy hemp vine.(3) a simple green background stands, the lower the proportion of the landscape trees and landscape trees are all pure stand scores of scenic beauty are low, and only when mixed in certain proportion between the two, we can show striking scenic forest landscape, landscape evergreen tree with the main color in a2:1ratio to maintain the maximum value of scenic beauty; significant changes in canopy surface can enhance the scenic beauty, therefore, to choose a different configuration tree species biological characteristics of tree species at the same time, the implementation of different age Mixed cropping pattern; landscape tree configuration view for the integrated distribution is high, so that the landscape distribution of both species dispersed and intensive; try to avoid the leaves of deciduous trees and flowering trees overlap the main landscape mixed mode a reduction of the proportion of the main landscape of gray.(4) color between the index and evenness index can play a complementary role. Scenic beauty of the forest landscape is positive, some color index of the low landscape evenness index is relatively high, indicating that with a uniform color to a certain extent, the low proportion of plants to make up for the lack of color.(5) the degree of scenic beauty of forest landscape values of the factors in the order of seasonal changes in the level of scattered canopy level, plaque, rich colors, texture and mixed crown, plaque was discernible. |
