Plant landscape is one of the important factors to reflect the environment quality of residential areas.The selection of green plants is the basis of plant landscape construction.The configuration of plant landscape of different green land types and the organic cooperation between plants and various landscape elements are also very important.This survey choose Dingxiuhuacheng district and Deyuanxincheng district from Jincheng as an example,through the way of field survey,data collection and analysis,to study the configuration of plant landscape of residential areas of Jincheng.The problems and deficiencies were summed up and combining with the characteristics of ecological environment of Jincheng,the suitable plant species of local stratified community and configuration mode was recommended.It would provide advice and reference to the greening of residential area of Jincheng for the future.The results show that:(1)According to the investigation on the application status of greening plants in Jincheng residential areas from four aspects,including plant species,life type,ornamental characteristics and growth status.It could be seen that the residential area of Dingxiuhuacheng were rich in plant species and representative.There were 38 species in 14 families,23 species of arbor,14 species of shrubs and 1species of herbaceous plant.There were 17 species of flowering plants and tree-bearing plants.According to the classification of flowering season,spring flowering plants were the most,followed by summer.And according to the classification of color of the flower,the red flower plants were the most.Otherwise,we could be divided the growth status into good and general.The number of arbor which had good growth status was 14 species and the shrub species was 9.(2)According to the investigation on the plant community structure and allocation mode of the three different types of green space,it could be seen that the two communities were all dominated by public green space and the plant configuration at different community levels was the most abundant.There were four main landscape patterns for public green space,such as arbor-shrub-cover plant,arbor-arbor-cover plant,arbor-cover plant and shrub-cover plant.And the main plant configuration mode was Ginkgo biloba-Poa annua,Ginkgo biloba-Buxus bodinieri+ Ligustrum vicaryi-Poa annua,Cedrus deodara-Poaannua,Lagerstroemia speciosa-Buxus bodinieri-Poa annua,Prunus cerasiferacv+ Buxus sinica+Buxus bodinieri-Poa annua and so on.There were two main landscape patterns for road green space,such as arbor-shrub-cover plant and shrub-cover plant.And the main plant configuration mode was Sophora japonica-Poa annua,Sophora japonica-Lagerstroemia speciosa+ Cerasus yedoensis-Rosa chinensis+Poa annua,Prunus cerasiferacv+Prunus persica-Rosa chinensis +Poa annua,Sabina chinensis+ Ligustrum vicaryi+ Buxus bodinieri-Poa annua and so on.The plant community structure and allocation mode of national locust green space was relatively simple.The main landscape patterns were arbor-shrub-cover plant and shrub-cover plant.And the main plant configuration mode was Sabina chinensis-Buxus bodinieri+ Berberis thunbergii-Poa annu,Sabina chinensis-Poa annu,Sabina chinensis+Buxus sinica+Buxus bodinieri+Berberis thunbergii-Poa annu and so on.(3)The investigation and analysis of garden elements of plant configuration were made from four aspects,such as the tiny terrain,water features,construction sketch,garden lamp and garden chair.The two districts were so different from no matter the community structure and plant configuration.It would be give priority to rule type configuration.Through the space arrangement of plant,it would be collocated with hard landscapes and made good landscape effect with clear lever.The plant landscape construction idea of residential areas would be fully reflected.(4)On this basis,the three problems were summarized in the plant landscape allocation of residential areas of Jincheng.For example,the selection of tree species is similar and the allocation mode is single,the local tree species is not attached enough importance and the utilization rate of dominant species are not high,the green space index is not standardized and the management lever is different.15 species of upper layer plants,17 species of middle layer plants and 4 species of lower plants were obtained as the suitable species of local stratified community.There are four suitable plant community structures for public green space,such as arbor-shrub-cover plant,arbor-arbor-cover plant,arbor-cover plant and shrub-cover plant with variety of construction mode and plant species.There are three suitable plant community structures for road green space,such as arbor-shrub-cover plant,arbor-arbor-cover plant and arbor-cover plant which has relatively simple plant construction.The application of arbor is more and the flower plant was less.There are two suitable plant community structures for road green space,such as arbor-shrub-cover plant and shrub-cover plant and it is collocated with evergreen plant and hedge plant. |
