Correlation Analysis On Landscape Spatial Pattern Of The Urban Park Green Space And Its Structure Of Tree Populations: A Case Study Of The Huagangguanyu Park In Hangzhou

It was quantified that the landscape pattern of the green space and its structure of tree populations in the Huagangguanyu Park, and the parameters of landscape pattern and tree populations structure of its green patches was calculated, and then their mutual Pearson relative coefficient and Prominence were counted too. According to the prominence it was estimated that the corrlelation of different parameters of its landscape pattern and that of its populations structure, and then the result was deeply analyzed and the relation of its landscape pattern and the structure of tree populations and their mutual adaptability was deeply discussed. The result show that 1:)This park is mainly occupied by these trees just like Cinnamomum camphora, Cedrus deodara, Magnolia grandiflora, Osmanthus fragrans, Camellia japonica and so on, and many native colorful trees are in the complementary. The Plant community styles in its vegetation patches not only have many commons with the forest landscape of west lake scenic resort, but also they are consistent in the selection of trees. 2) Its landscape pattern is complex and the patches of different styles have different spatial distribution styles. Some is assemble and some is dispersed. The matrix is the patch style -not near the water and flat and sparse forest. All styles of the vegetation patches are distributed with assembly and decentralization in its figure and distribution manner, which is according with the ideal model of landscape pattern. Its landscape pattern and structure of tree populations are adapting to its functions, Which is faver to decrease the disturb from people. Just like that the core patch which is not adjacent to water and hilly woods has the flat edge, near round shape, high trees diversity and abundant native trees, which can reduce the external disturb and protect the native trees. In addition, the matrix in the landscape is the patch that is flat, not adjacent to water and scatter woods has low fragmentation degree, smooth edge and near ellipse shape, which is adapted to matrix. All patches adjacent to water are excotone and they have twist edges and narrow figure, which issuitable with the function of the frequency of exchanging the matter and energy, what's more, these patches are mixture in the plant community styles, which is according with the importance character of the excotone which is that many system coexist.3): The dissimilarity of plant community is key factor in composing the landscape heterogeneity. Dissimilarity of tree canopy pre area is the character of landscape heterogeneity of the different styles vegetation patches. Different community styles distributed in different green patch styles and among the same style of green patch they have high plant community dissimilarity index. In a word, the landscape heterogeneity exist in different scales and so the green space has a landscape pattern which is much favor to the stability of ecosystem.4): Its green patch's figuration index and fractal index are correlating with its tree diversity index and the shape design of different styles patches in this park is adapted to the planning of its trees diversity.5): Its green patch's figuration index and fractal index are not correlating with its plant community dissimilarity index and so the design of the landscape heterogeneity in the interal patch is not suitable for its pattern.
