Study On Community Characteristics And Landscape Application Of Camellia Chekiangoleosa.

An overall analysis of the species composition, physical structure, species diversity, physical and chemistry character of soil and landscape application of the Camellia chekiangoleosa community was provided in this paper. This study was based on the comprehensive investigation of 20 sample plots of the area about 10×10㎡,distributing in Kaihua, Zhejiang province, Xiapu, Fujian province, Nan Feng, Jiangxi province, Yuexi, Anhui province.1. The species composition and floristic characteristics of the community. There are 75 families, 48 genera and 114 species of the plants in the plot. (including subspecies taxa), of which 4 families, 4 genera and 5 species of ferns, 2 families, 2 genera and 2 species of gymnosperms, 42 families, 69 genera and 107 species of angiosperms. Those 5 families cover 43% of the sample plots of the species. The community plant species were pretty rich, and components of fauna was complex, tropical elements of the geographical component of genera was less than the proportion of temperate zone’s ratio.2. The community appearance. The main life form of the plants were phaenerophyta plants and there was no big phaenerophyta plants, with the main leaves nature of small, simple leaf, leathery and non-entire leaf.3. The age structure of Camellia chekiangoleosa population was stable, and more the seedlings with sound updated. The vertical structure of the community was integrated, big arbor was fewer without continuous crown of arbor layer; and high percentage of shrubs and small trees, which was high density; the layer of shrubs was high coverage and density with rich species; while the herb layer was rare species, but give first place to ferns and carex plants, with high coverage of individual species.4. The species diversity. Comparison of the Margalef richness index, Simpson diversity index and Shannon-Wiener index in various communities of tree layer, shrub layer and herb layer, obtaining the same result that the different layers of the species diversity in a diminishing sequence was the shrub layer, tree layer, herb layer.5. The suitable soil of Camellia chekiangoleosa. The suitable soil for Camellia chekiangoleosa was the acid soil, pH 5 to 6, pH 4.5 to 6.5 was the common soil. The mean soil nutrient of the community was: organic matter 7.56%, hydrolyzed N 125.26mg/kg, available P 5.87mg/kg and available K 90.15mg/kg.6. The garden application of Camellia chekiangoleosa. The Camellia chekiangoleosa can be used as the key species of border tree, shade tree and residential landscape. The planting pattern can be alone, group planting, scatter planting or as a form of high fence. The Simulation of Camellia chekiangoleosa in garden application should be closed to the habitat conditions of natural community, creating suitable soil and climatic conditions, selecting the composition and combination under natural conditions, so as to improve the species diversity and maintain the community stability.
