The Plant Configuration And Landscape Evaluation Of Xianghe Landscape Belt In Quanjiao County, Anhui

In this paper, using landscape planning, landscape design, botany, landscape ecology, psychology, aesthetics and and some related theory, use Quanjiao Xianghe landscape belt as research object,based on the status survey of designing and landscaping plants, through seasonal, hue, species richness in plants (S), the dominance index (D, Simpson index), analysis index (H, Shannon-weiner, diversity index and evenness index (E, Pielou index) to the corresponding plant, use the AHP method to evaluate landscape value of 22 sample plot in Xianghe landscape, points out the existing problem about plant arrangement and landscape of Xianghe landscape, put forward updating opinions and suggestions, aiming at putting the Xianghe landscape belt into riverside landscape belt with the Quanjiao characteristic.Research results are as follows:1.It has 89 species plants in Xianghe landscape,divided into 40 families and 66 genera.44 species of trees,28 species of shrub,17 species of herbaceous plant. The ratios of deciduous species and evergreen species approximately is 3:1,the ration of native plants and exotic plants approximately is 1:2.2.Xianghe landscape configuration mode with various points of the main for the arbor -shrub-grass, combined with the scenic spot arrangement, every point has the well ornamental characteristics, but the best time to visit concentrated mainly concentrated in the spring and summer, spring flowering plants in the larger proportion, meanwhile more centralized, view fruit plant species are less, autumn landscape color is single, emphasis on red, so the winter landscape looks depression.3.It has very few species about high frequency application trees in Xianghe landscape, comprehensive analysis, there are high important value about the frequency tree species generally.4.The species richness mean value is 6.23 in 22 type place of Xianghe landscape; The Simpson evaluation index mean value is 0.55, the highest value of 0.85 is 17# Lagerstroemia indica -Kerria japonica-Oxalis community, the minimum value is the 18# Prunus subhirtella-Wisteria sinensis- Spiraea japonica community; the highest diversity index value is 1.896, the minimum value is 1.156;The minium evenness value is 1# Pinus massoniana Lamb -Acer rubrum-Festuca elata community,0.564, mainly because the shrubs less hierarchical, the lawn was fired,10# Phyllostachys aureosulcata -Yucca gloriosa-Iris tectorum community evenness index was only 0.609, mainly because the Iris tectorum planting density is small, not into the ground and bare. Through the above analysis we can understand, most communities had higher species richness and evenness, community showed consistent, also shows that if the higher species richness of communities, dominance index, diversity index, evenness index is relatively high.5.In the landscape value assessment, I plant landscape plots has five,4#,5#,7#,10#, 19#, accounting for 22% of the total evaluation plots, II landscape plots has 14, accounting for 64% of the total evaluation plots, grade III plots has 4, accounting for evaluation 14% of the total number of samples.
