Research On The Green Space Planning Of YanHe Village, Gucheng City Based On The Investigation Of Plant Resources

Along with the development of new rural communities construction, the rural housing refomation and infrastructure construction have gradually gained more and more attention, but usually the construction of rural green environment has been easily ignored. Plant, as the only living landscape element, plays a vital role in the environment constrution. On the basis of surveying to the major resource of plant species, plant communities and greening situation, the paper systematically planed the green plant, landscape structure and application of simulated artificial community. The results were giving as following:(1) Totally there are 354 species,279 genera and 120 families of vascular plants, including 144 species,133 genera and 89 families of cultivated plants; 261 species,210 genera and 105 families of wild vascular plants (native plants). Gramineae, Compositae, Rosaceae and Papilionaceae are four most important families, contributing 23.69% of the total species.(2) For native plants, the proportion of trees, shrubs, herbs, lianes species is 1.9:2.5:4.6:1; and that of evergreen trees, deciduous trees, evergreen shrubs, deciduous shrubs is 1:6.1:2.7:6.6.(3) The analysis of the families distribution pattern demonstrates 11 types, cosmopolitan families cover the largest (35.11%), and pantropic families, north temperate families exist in turn. The analysis of the genera distribution pattern demonstrates 14 types, the north temperate genera cover the largest (21.72%), and pantropic genera, E.Asia genera exist in turn. The temperate zone elements take a major proportion demonstrating a trend from subtropics genera to temperate genera.(4) There are 14 ancient and famous trees in Yanhe village, including 1 species of the first grade and 13 species of the second grade.(5) There are 8 species of rare and endangered wild plants in Yanhe village, including 2 international plants,4 national plants and 2 provincial plants.(6) There are 216 wild ornamental plant resources in Yanhe village, including 48 trees,54 shrubs,24 lianes,78 herbs and 12 pteridophytes.(7) In Yanhe village, the plant communities can be departed into 6 vegetation types, 15 formations and 18 associations. There are 8 deciduous broad-leaved forests contributing 44.44% of the total associations.(8) There are 123 greening plants species belonging to 110 genera and 73 families. The proportion of trees, shrubs, herbs, lianes species is 5.3:4:5.1:1, and that of evergreen trees, deciduous trees, evergreen shrubs, deciduous shrubs is 1:3.2:1.8:1.4. Besides, the greening ratio of native plants is 21.07%.(9) On the basis of investigation to the resource and communities, the paper systematically planed the green plant of Yanhe village, and designed the landscape structure of "inside:one heart, two belts, four areas, nine points; outside:two wings supply with each oter and ecologically permeate", whatelse the paper also discussed the application of simulated artificial community.
