Analysis on Landscape Pattern of Park System in Meizhou

The park landscape pattern in Meizhou was analyzed by using the landscape ecological principles and methods.The results showed that the distribution and structure of the parks in Meizhou were not much reasonable.From the viewpoint of the areas of green space,the area of the city parks and district parks accounted for 89.97% of the total while the other green spaces accounted for only 10.03%.The heterogeneity indexes of city parks and district parks were much higher than that of the other green spaces,and the fragmentation indexes from high to low were in the order of roadside green space,community parks,squares,linear parks,city parks and district parks.From the viewpoint of distance index,the gregariousness of patch landscape at new-built town and northern bank of Meijiang River was more obvious than that at southern bank of the river. As to dimensional index,that of the 5 kinds of green spaces in Meizhou city was low(<1.25),with the city parks and district parks the highest(1.236 8) and the square the lowest(1.047 2).To improve the landscape pattern of city green spaces and the environment in Meizhou,focus should be put on the construction of community green spaces,square green spaces,and linear parks by well allocating all kinds of parks and green spaces and avoiding reunion distribution,as well as paying attention on landscape diversity and fractal dimension.
