| The subject of the application of3S technology, and Community and Landscape Ecologyresearch methods in Fuzhou West Lake Park in Mountain Park, Min River Park (South RiversidePark, North Riverside Park), especially the South Riverside Park Plant CommunityCharacteristics, green landscape ecological characteristics, as well as green, eco-efficiencyresearch and in accordance with the basic theory of the ecological garden theory, niche theory,landscape ecology theory and community learning, combined with the Fuzhou park greenbuilding status and the problems raisedFuzhou city Park green ecological construction modelsand frameworks. The results are as follows:1.Green parks community composition: total of177kinds of plants under the69families,124genera, tree34families,65genera and89species, mainly Sankoh, Magnoliaceae, Rosaceae,palm plants, shrubs,33families,50genera and62kinds topalm, the mallow family, Gramineaeowners, herbs,15families,22genera and23species, mainly to the Liliaceae, Amaryllidaceae,Fujimoto3families and3genera and3species.Analysis showed that the green vegetation types:traditional native species in Fuzhou city park green plant applications at this stage in the gradualmarginalization of the excessive pursuit of the aesthetic landscape, ignoring the protection anduse of native tree species.2．Green parks community characteristics of species diversity: average Fuzhou city of greenparks community tree9, Simpson dominance index was an average of0.567, the diversity indexof Shannon-Wiener diversity index is an average of1.121, the Pielou evenness index was0.824shrub layer an average of7, Simpson dominance index was an average of0.195, thediversity index of Shannon-Wiener diversity index is an average of0.9925, the Pielou evennessindex was0.846, the richness of the herb layer is an average of4.17, Simpson dominanceindexThe average diversity index of.397, the Shannon-Wiener diversity index is an average of0.65, the Pielou evenness index was0.732. West Lake Park tree layer, shrub layer, herbaceouslayer index are more evenly, South Riverside Park, North Riverside Park, the tree layer and shrublayer index value higher than the herbaceous layer of the index, plant community diversity fromhigh to low Sort of West Lake Park at Hill Park, South Riverside Park, North Riverside Park.Visible Fuzhou each park species diversity, the contrast subtropical natural plant species diversity characteristics, the Fuzhou green parks the status quo from the ecological requirements of thebuilding there is a large gap, so in the future in the ecological construction of the park greenspace to increase plantselecting and applying research.3. Vertical structure of community of green parks, trees+shrubs, trees+herb, shrub+herband single plantation, the tree layer of plant average height of8m~10m, mainly banyan,camphor, lemon eucalyptus, kapok, Livistonafalse betel nuts, white orchids, etc.; the shrub layer,the average height of1meter, Huang Jinrong, gold leaf, cuckoo, golden false forsythia, safflowerfollowing the wood, etc.; herb layer height of about10cm~50cm, SyngoniumManila grass,Ophiopogon, mosaic Yan Shan ginger and so on. The level of plant communities in the agestructure of West Lake Park, Park at Mountain Park is better than the South Riverside Park,North Riverside Park. Fuzhou Park Plant Communities in the bush was artificially pruning.Level structure characterized by the mosaic structure of small community-based. Overall, thevertical structure is relatively simple, mostly single or simple two-tier, less compositemulti-layered structure, while the level of structural diversity, so in the future to increase thevertical structure of configuration efforts to green parks.4. Landscape of green parks woodland landscape, landscape diversity index from high tolow for the South Riverside Park, North Riverside Park, West Lake Park, Hill Park, were0.6931,0.6769,0.6039,0.5885overall diversity index is not high,The abundance of green parksoverall crushing larger number of small and medium-sized plaques, small size, reduced plaqueinternal habitat, increased isolation, lack of communication between the districts plaque.Not yeteffective artificial landscapes and natural landscapes in harmony together, plant communities inseasonal variation is not obvious, a single color, canopy line is a high degree of similarity thanthe too monotonous.5. Different green parks, the environmental impact of different performance than in HillPark and North Riverside Park Riverside Park green space ecological benefits for the West LakePark and South. The combination of tree+shrub+herb plant communities play eco-efficiency ishigher than the trees+shrubs, trees+herb, shrub+herbs and single-layer artificial forest. ParkPlant Communities in the environmental impact of summer and winter than in spring and autumn.Comparison of different parks, communities of different structure, different seasons of theecological performance differences analysis of the performance of a complex hierarchy of high landscape diversity park green space ecological benefits for the community composition best.Quantitative indicators of the ecological benefits of play and green parks community, communitystructure, landscape structure characteristics are closely related. Therefore, the construction ofgreen parks should consider these factors.6. South Riverside Park green eco-construction of the prototype analysis: communitycomposition, plant78species belonging to66genera of41families, including angiospermsaccounted for the vast majority of a total of38families,63genera and75species, the totalnumber of species96.2%. The gymnosperm3Section3are three kinds, the total number ofspecies3.8%. Trees Sankoh, Rosaceae, Leguminosae, Euphorbiaceae, Myrtaceae, palm plantsbased. Into pieces planted on the structure of the green community level, a large area ofdistribution of guava, Araucaria, false betel nut, banana, bamboo, Lagerstroemia speciosa, etc.,focus on the vertical structure of trees, shrubs, understory vegetation mix. South Riverside Parkgreen overall diversity index is good, but its diversity in the local terrain is low, the futureconstruction should focus on focus on the regional analog of the natural environment to create, toreduce the single plant community woodlands, and to strengthen local green eco-building efforts.7. order to achieve eco-city construction requirements, Fuzhou, green parks to speed upecological construction, according to the theory of ecological city, ecological parks andecological garden, the construction of Fuzhou green parks Fuzhou green parks ecologicalconstruction should take the following strategy:(1) the basic principles of green parks ecologicalconstruction adhere to the overall, coordination, circulation, authigenic ecology theory as a guide,highlighting the natural and ecological features, build appearance to meet the aesthetic value, theinternal structure to meet the ecological requirements, simulate natural features of the parkgreenlandscape.(2) types of configurations to native tree species in the main established Fuzhou greenparks backbone species, play the advantages of Fujian Province, the traditional five categories ofFagaceae, Lauraceae, Magnoliaceae, Theaceae, Hamamelidaceae;artificial create the perfectnatural growth of vegetation on the structural design, the formation of a complete communitystructure, species diversity, biomass, chemotaxis steady state, the latter in full compliance withthe laws of nature, less manually managed green. Strengthen the protection of large landscapewoodlands in the landscape pattern, reducing human disturbance factors, and restore the naturalecological succession, as far as possible to reduce the number of artificial landscape patches, green parks design style should be harmonized with the overall urban landscape.8. Fuzhou Urban Green Space and ecological construction in the future, into a public parkshould be a gradual development of post-maintenance and reasonable transformation of the greenparks concept of ecological building design should be used for new parks, Fuzhou city greenparks, naturalization shift towards ecological, combined with the Fuzhou characteristicsof thewater network and the network, in accordance with significant mountain dew, see the green"eco-thinking, and improve urban green space ecosystem. While speeding up park greenecological construction laws and regulations to improve and strengthen the theoretical study ofthe ecological construction of green parks, ecological construction funding to increase greenparks, and comprehensively promote the ecological concept of the social culture of the wholesociety is a good atmosphere of ecological construction. |
