| Under the background of rapid urban development,urban agricultural parks have become one of the most important ways for stabilizing the balance between urban and rural development.The paper studies Xi’an urban comprehensively,which is conducted from raising and analyzing of problems to solving of problems.According to the list of Xi’an leisure agriculture above municipal level,the methods of field research and literature review,54 samples are selected for the further study.Evaluations are performed from ecological networks,agricultural resources and park landscapes.The results of evaluations show are as follows.Ecological networks of urban agricultural parks are poor;urban agricultural parks are not fully integrated into rural and urban green space system;the ecological value of urban agricultural parks has not been fully realized.The agricultural resources of the parks are partially coupled;the agricultural industry has much room for development;parks don’t take full advantage of producing function.The landscape in the park is not rich;the quality of landscape needs to be improved;the life function of the urban agricultural parks cannot be fully exerted.According to the results of evaluation,the paper puts forward the overall strategies of development.Firstly,based on the present features of resources,we put forward the macro layout of urban agricultural parks according to the utilization and connection of patch at the macro level of ecological network.During the construction process of buffer strips in urban fringe,the buffer strips in urban fringe along the northern Weihe River are constructed which can be used to build large-scale agricultural ecological parks and sightseeing agricultural parks.In the eastern Bahe River and the Chanhe River,according to narrow forest belt and the limitation of the land resources,the agricultural ecological belt park and small farm family music can be constructed along the line which can connect the existing network system.Although the agricultural land is vast in the southwest suburbs,but the buffer barrier is weak and the patch connectivity is poor.Based on this,the overall layout of urban agricultural parks embedding farmland and woodland and large scale or medium scale agro ecological parks and sightseeing agricultural parks should be set up,and Ecological corridor or culverts should be constructed horizontally in the road which can link green patches.In convenient transportation areas in suburbs,agricultural science and technology demonstration garden and farmer household an be built to increase green patches and linking corridors.In outer suburbs,rural complexes are encouraged to build in rich villages and towns which can build and product large green patches.Secondly,in terms of the utilization level of meso agricultural resources,the construction of urban agricultural gardens in the urban areas should be dominated by vegetables and flowers,and fruit trees should be adorned to form rich and stable plant community at the middle level of agricultural resource using.According to the present agricultural resources in suburb,agricultural resources should be coupled and sustainable agriculture industry should be developed which can make counties characteristic and differentiation.The development direction should be transformed into high-tech agriculture,the agricultural culture experience and the creative agriculture in some couples which have less agricultural resources and the main agricultural type is grain crops.Large-scale urban agricultural projects should be encouraged in order to forming a large-scale agricultural industry in some couples with abundant agricultural resources.Thirdly,based on the evaluation results of landscape towards urban agricultural parks in Xi ’an,and cases at home and abroad,we summed up the planning and design guideline and park development strategy from the theme positioning,road plant building sketch water function zoning,urban plantations scientific planning and design of sustainable harmonious analysis at the micro level of landscape construction. |
