Evaluation And Optimal Design Of Productive Plant Landscape In Hangzhou

With the advance of urbanization, population growth, shortage of resources, environmentaldegradation and many other negative issues have appeared, resulting in the loss of agriculturalfactors, agricultural degradation, disappearing farmland. The health of city is affected, then theawareness of returning to the countryside is gradually warming, productive plant landscape isemerged. Productive plant landscape can improve the structure of green space system, create avariety of landscapes, meet the multi-faceted capabilities needs, and promote agricultural tourismsystems and agricultural production systems to the symbiosis, then realize diversification ofagriculture, accelerate the integration of urban and rural areas. The paper puts the productive plantlandscape of Hangzhou as the research object, analyzes its resource characteristics, functionalefficiency.Selected Ba-gua-tian and Mei-jia-wu as the example, optimize the design based on theevaluation of SBE.The main results of this paper:1.Through the investigation of production plant landscape of Hangzhou, it can besummarized as edible landscape, timber landscape, medicinal landscape. And the problems in thedevelopment of rural and urban green land summarized as: how to realize the unity of productiveand ornamental; how to extend the connotation of participation; how to scientific planning andmanagement.2.Ba-gua-tian and Mei-jia-wu were estimated by the SBE, the results shows the significantfactor’s ranks from high to low is color and seasonal change,landscape forms,cultural artisticconception,space arrangement, should strengthen the features of the landscapes; the SBE values oftee garden of Mei-jia-wu is high, but the other landscapes are low, the significant factor’s ranksfrom high to low is cultural artistic conception,landscape forms,space arrangement,color andseasonal change, should enhance the connotation of tea culture and rich landscape forms.3.Based on the SBE evaluation, optimizing the designs of Ba-gua-tian and Mei-jia-wu. ForBa-gua-tian, crops should be coordination arrangements, the choice of crop varieties should benovel, ornamental aquatic plant species should be increased. For Mei-jia-wu, the optimization oflandscape should take seasonal, color into account; functional design should take tee productionarea, specialty varieties display area, visitors experience area and so on into account, and optimizegarden architectures, garden roads and waterscapes, improving the culture artistic beauty and a variety of landscape form. Finally, summed up four productive plant landscape constructionstrategies:scientific planning and design,the unity of ornamental and productive,activity design,business management, promoting agricultural production and tourism system to coordinateddevelopment.
