The Research On Village Greening Model And Application In Huzhou Area Of Zhejiang Province

The construction of rural greening is an important means to implement the strategy of rural revitalization;The rural greening landscape not only can comprehensively improve the rural ecological environment,but also drive the development of rural tourism,orticulture healthcare recruitment,forest tourism and other related industries,promote economic growth in rural areas,and enhance the happiness of the majority of farmers.Zhejiang,as the birthplace of the construction of beautiful villages in China,has launched rural greening and beautification actions,such as the construction of "thousands of trees in one village" and "large regional gardens",to improve the ecological environment in rural areas since 2003,and has made certain achievements and experience.However,in the process of rural greening and beautification construction,due to the lack of scientific and reasonable early planning guidance in some areas and the lack of awareness of greening,the village greening model blindly copied the urban landscape greening model,the selection of greening plants was unreasonable,and the rural greening landscape lacked local regional characteristics.In order to comprehensively improve the level of rural greening and beautification and create a rural greening landscape with local characteristics,this paper takes the village greening in Huzhou as the research object under the background of national beautiful rural construction,based on the field survey of different types of villages in Huzhou,combined with the characteristics of different types of villages in Huzhou,such as location distribution,economic development level,industrial structure,etc,Carry out field research on rural greening landscape in Huzhou,and master the current situation of village greening plant configuration through the analysis of the application characteristics of rural greening plants and the characteristics of rural plant landscape construction;On this basis,AHPanalytic hierarchy process is applied to build a comprehensive evaluation system of rural green landscape suitable for Huzhou area,and 14 typical villages in Huzhou are evaluated comprehensively;Finally,according to the field survey,combined with the greening characteristics of different types of villages in Huzhou,different greening transformation models are proposed for different types of villages,and the greening and beautifying transformation of Ximu Village is taken as a practical case,in order to provide some reference for the rural greening and beautifying in Huzhou.The main research contents of this paper are as follows:1.Through the research of relevant literature,based on the definition of the basic concepts and relevant theories of rural greening and the research trends on rural greening at home and abroad,guided by the theories of landscape architecture,landscape ecology,landscape aesthetics,environmental psychology and many other disciplines,it provides some theoretical support for the relevant research on rural greening in this paper.2.On the basis of field research on different types of villages in Huzhou area,combined with the greening characteristics of different types of villages in Huzhou area,the method of combining different types of village greening sample plots with sample plots was adopted to carry out field research on the plant landscape in the greening area of 14 typical villages in Huzhou area;The investigation results show that there are rich varieties of village greening plants in Huzhou area.There are 171 different types of plants in different types of village greening plots,belonging to 69 families and 135 genera,including 49 common trees,31 shrubs,65 herbs,16 vines,5 aquatic plants and 5 bamboos,accounting for 28.65%,18.13%,38.01%,9.36%,2.92%and 2.92%of the total number of plants investigated respectively;Among them,the tree species with higher application frequency in the arbor layer include Cinnamomum Camphora,Magnolia grandiflora,Osmanthus fragrans,Ligustrum lucidum,etc.The tree species with higher application frequency in the shrub layer include Loropetalum chinense,Rhododendron simsii,Photinia X Fraseri),Nerium oleander,etc.The plants with higher application frequency of herb layer include Ophiopon bodinieri,Trifolium repens,Zoysia japonica,Petunia hybrida,etc;According to the field survey,the overall plant landscape construction of the village greening in Huzhou area is dominated by the "arbor shrub grass" multi layer green plant community.The spatial distribution of different types of green plants is dominated by garden green plants(89 species),followed by public green spaces(64 species),road green spaces(36 species),and waterfront green spaces(35 species);From the perspective of the growth status of village greening plants,the overall growth status of village greening plants in Huzhou area is good,including 124 plants in good health,accounting for 72.51%of the total number of plants investigated;From the perspective of the overall construction characteristics of plant landscape,the construction of rural greening plant landscape in Huzhou area is mainly based on local plants.Different types of greening spaces have their own characteristics,rich greening levels,strong rural idyllic atmosphere,and more attention is paid to the protection and utilization of original ancient trees.3.Combined with the field investigation of village greening,the AHP analytic hierarchy process is applied to establish a comprehensive evaluation system of rural greening landscape,which includes 4 criteria level indicators of ecological benefits,aesthetic benefits,social benefits and economic benefits and 16 evaluation factors.According to the weight value,in the construction of rural greening in Huzhou,the ecological benefit(B3)weight(0.3675)>economic benefit(B4)weight(0.3075)>social benefit(B1)weight(0.1775)>aesthetic benefit(B2)weight(0.1493)of rural greening landscape;In the factor layer of ecological benefit evaluation,the highest weight value is the species diversity of greening plant landscape,reaching 0.3932;In the economic benefit evaluation factor layer,the highest weight value is that green landscape drives economic development,reaching 0.4434;In the socialbenefit evaluation factor layer,the highest weight value is the regional cultural characteristics of green landscape,reaching 0.6098;In the factor layer of aesthetic benefit evaluation,the highest weight value is the landscape richness of green plants,reaching 0.3121;According to AHP comprehensive evaluation model,the greening landscape of 14 typical villages is comprehensively evaluated from four aspects of ecological benefits,aesthetic benefits,social benefits and economic benefits.The results show that the greening construction of villages in Huzhou area is in good condition,including 3 villages with Class Ⅰ greening landscape,which are divided into Fangyi Village,Beitang Village and Lujia Village;There are 5 Grade Ⅱ green landscape villages,including Guzhu Village,Digang Village,Xinglong Village,Shuangyi Village and Miaoshan Village;There are 4 Grade Ⅲ green landscape villages,namely Dongheng Village,Dazhuyuan Village,Xitang Village and Shicong Village;There are two Grade Ⅳ green landscape villages,namely Lishan Village and Dachong Village.Based on the comprehensive evaluation results and field investigation,it can be seen that the greening of villages in Huzhou is in good condition.Most villages have been transformed into rural greening as a whole under the promotion of the construction of "beautiful villages".The greening coverage of public areas and roads in the village is high.The greening forms of rural courtyards are diverse,the types of village greening plants are rich,and the stability of greening plant communities is high.4.According to the characteristics of village greening in Huzhou and the differences in regional distribution,economic development level and industrial type of different types of villages in Huzhou,the greening transformation mode suitable for different types of villages in Huzhou,such as plain water network villages and hilly mountain villages,is proposed.5.Combined with the full text of the research on the theory of rural greening and the field survey of rural greening in Huzhou,taking the greening and beautifying transformation of Ximu Village as a practical case,combining with the greening characteristics of Ximu Village,planning the village plant landscape with the concept of "a large garden",and planning and designing the plant landscape of Ximu Village’s rural greening and beautifying transformation.
