The Research Of Ecological Planning Of Zuojiang River Banks In Longzhou Guagnxi

On the basis of field investigation of Zuojiang River banks in Longzhou Guangxi to analysis the landscape pattern and the historical and cultural landscape of the study area, and based on the analysis results present ecological planning strategy, the main process of the research includes the following results:1. The results of landscape pattern of Zuojiang River banks analysisThe fundamental landscape type characteristic analysis indicate:The total area of site is26264.86hm2, the shrub forest landscape as the pattern of the study area plays a leading role in the site, its area is11884.39hm2to be maximal and continuous distribution in the study area. The paddy field, nonirrigated farmland and forest landscape are the main plaque of the study area and the other smaller landscape patches scattered in the planning area. Zuojiang River is an important river corridor runs through the study area.The landscape structure characteristics analysis indicate that beside the road landscape the highest of the shape index and fractal dimension are the paddy field, nonirrigated farmland and forest landscape to be complicated and weak stability, and relatively the waters and residents landscape to be simple and high stability.The landscape diversity analysis indicate that the diversity index is1.5121, the landscape fragmentation index is0.0228, the maximum diversity index is6.3936, the evenness index is0.7272and the dominance index is7.9057. Also shows that the study area is controlled by minority single landscape type and landscape heterogeneity of the study area is low.Landscape areas and the study areas similar analysis indicate:The the similarity indexs between the study area and Xiangshui, Shangjin landscape area are highest and the otherness are minimal, so the two landscape area are planned to be the core planning area. The Badeng landscape area is planned to be key protection area as its similarity indexs is the minimal one be0.7231. The similarity indexs of Chenxiang and Baixue landscape are lower so the landscape is distinctive, and is planned to be importance planning area.2.The analysis of historical and cultural landscape of banks of Zuojiang RiverThe analysis of historical and cultural landscape indicate:The main landscape types includes the Zuojiang River and Mingjiang River scenery as the representative of scenic landscape, the Ningming and Mianjiang Huashan mural as the representative of the mural landscape, the Mianjiang wall hanging coffin as the representative of the wall hanging coffin landscape, the Shangjin old street as the representative of the historic district landscape and the Zixia hold and the cultural life of the Zhuang as the representative of the vernacular cultural landscape.3. The ecological planning strategy analysis of banks of Zuojiang RiverOn the basis of the landscape spatial pattern and the historical cultural landscape analysis conclusion of banks of Zuojiang River, proposed the strategy to renovate matrix model and patch, to rebuild river and road corridor. And present the protection of historical and cultural landscape authenticity and the construction of historical and cultural landscape corridor to ensure the integrity and continuity of historical and cultural landscape along banks of the river.4. Eco-landscape planning practice of banks of Zuojiang RiverBased on the relevant laws and regulations to propose the ecological planning strategy of banks of Zuojiang River.The strategy of the study area is divided into5functional areas, which are Shangjin ecological health leisure vacation Island, Chenxinagjiao Pastoral leisure holiday camp, Baixue landscape rural health park, Zhuang Town and Badeng ancient Luoyue tribe village, put the landscape structure to be "one axe, five districts " area. By means of landscape system optimization, green river and historical and cultural landscape corridor construction to improvement of landscape space system. And the landscape quality improvement planning of infrastructure, public service and reception facilities, flood control safety pattern and environmental protection.
