Design of ecological plants munity.Waterfront plants landscape of Jianghang GrandCanal is of continuity in spatial structure. Theecological and landscaping functions of greenlandscape have been achieved through plants.So, the design of waterfront plants munityshould aim to optimize ecoenvironment andimprove environmental quality. In accordancewith landscape ecological theory, it needs toimitate natural ecological population structure,primarily plant native species, take account ofthe diversity of plant munity, and selectproper trees. In the perspective of the generallandscape of waterfront green belt, it shouldpursue the change in the unity, and creatediversified and coordinated plant landscapesconsistent in style[3]. (1) Selection of landscaping plants’ species.Urban waterfront green land is a public openspace in which natural ecosystem is integratedwith artificial construction system, with richlandscape information. Plant landscape shouldtake account of the ornamental effect of theland and also the landscape effect of the water.Green tree species at the riverside should beable to resist to wetnes, and also correspondwith beauti?cation requirement. It should select native tree species, andapply arbors, shrubs, herbs, ground cover plants,climbing plants and ?owers in accordance withecological botany. In order to make plantslandscape along the bank of the canal forma unified and continuous integrity, it shouldconsider selecting Populus , Cinnamomumcamphora , Osmanthus fragrans , Metasequoiaglyptostroboides , Salix babylonica , Forsythiasuspense and Ginkgo biloba as the fundamentalkey based on original plants and different stylesof tree species in different regions. Besides, itneeds to increase public green lands in additionto green lands close to the residential area. (2) Arrangement of waterfront landscaping.In waterfront landscape arrangement ofJinghang Grand Canal, it should adopt naturalecological design. Based on traditional plantlandscaping, it should pay attention to therequirement of plants’ ornament. By biningwith local environmental features, it needs toimitate the natural formation process of watersystem and create an ecoenvironment suitablefor the growth of waterfront plants. At the sametime, it needs to regard the inherent ecologicalmunity, conduct the restoration and breakthrough original formulized pattern, so thaturban waterfront green land will be full ofnatural interest, finally improving ecology andinterestingness of urban waterfront green land. Design of road transport network. Roadtransport network is the morphological skeletonof urban waterfront landscape and the linkbetween water and land. Therefore, the design29of urban waterfront landscape road transportnetwork should be bined with the actualsituation of water system, so as to create ahumanized road system to enlarge riversidegreen land as far as possible, forming continuousgreen landscape belt. At the same time, it shouldenhance the relation of water with surroundinggreen lands, landscape sketches and servicefacilities, so that citizens can be close the waterto the largest extent[6] and meet their waterloving demand. (1) Waterfront footpath. To create tranquiland fortable atmosphere, it should seta waterfront footpath along the riverbank,echoing with the water, and meeting tourists’need for walking and appreciating. Primaryfootpaths contain steps, stepping stones,waterside plats, trestle roads and so on. Tomake people better feel the capaciousnessof the water and contact with the water,waterfront footpaths should be lowed down.If two or more waterfront footpaths are to beset, they should be designed in different formsto manifest different landscapes. Waterfrontfootpaths can divide the green belt into differentpatches, on which some pergolas, feature walls,lamp posts and sculptures should be designed toenrich waterfront landscape. At the same time,it should add some proper plants arrangementsalong waterfront footpaths to create naturalecological landscape[3]. (2) Vehicle road system. An open waterfront area should have convenient transportaccessibility and perfect transport network.It should increase public transport routesaccessible to the waterfront area at the westbank of Jinghang Grand Canal, perfect publictransport system of the waterfront area andappropriately set motorized vehicle lane andnonmotorized vehicle lane when the waterfrontgreen land is wide enough. In order to ensurethe security of pedestrians, the vehicle laneshould be separated from waterfront footpath.In addition to waterfront footpaths, it canappropriately apply pollutionfree battery tourpath for tourists’ long distant tour. Revetment processing. The revetment isthe border between land and water. Comparedwith the water, it is the frontier of the land.Good revetment design can not only help tocreate a good waterloving space and environment and attract tourists, and well protect ecoenvironment of waterfront green belt. Due to historical reasons, the revetmentof the west bank of Jinghang Grand Canalis basically dominated by concrete and stoneblocks with cement mortar. Landscape effect ispoor and ecological function is difficult to bedisplayed. In accordance with the features oforiginal revetment in different sections, it shouldadopt natural primitive revetment, naturalrevetment and arti?cial natural revetment, so asto improve the waterfront landscape image andrestore ecological balance. Height control of waterfront buildings.The research area is dominated by residentialand industrial lands, so it needs to control
