The Research On Ecological And Landscape Reconstruction Of The Yellow River Floodplain

Aims:Through the ecological and landscape reconstruction, the sustainable development of the Zhengzhou Yellow River Floodplain was realized. Methods:First the materials including the research area'present situation chart and topographic diagram, the remote sensing phantom and the yearbook and so on related statistical datas were collected and carried on the scene investigation. Taking the Zhengzhou water conservancy records, the traveling plan, the ecological environment protection plan, Hui Ji district national economy and social sustainable development summary and so on datas and the country' related laws about the forest resources conservation, the water resource conservation, the wetland protection, the water and soil conservation, the flood prevention, the wild animals and plants protection, the environmental protection as well as the international biodiversity protection pact and so on as the bases. Through analyze the Zhengzhou Yellow River Floodplain'latent ecosystem service functions and values, the reconstruction primary objective of the ecological and landscape were determined. Under the instruction of ecological principle, the landscape ecological principle as well as the ecological engineering principle, union target localization, takes the landscape ecological security pattern analysis and the ecological suitability analysis as the main methods, function districts were definited. The suitable functions of the place were determined by selectting soil, water source, vegetation, animal, and ground supporting capacity, scenery and so on targets with the ecological suitability appraisal law. Landscape structure of the Zhengzhou Yellow River Floodplain was reconstructed by using "the centralism and the dispersed phase unify" the landscape pattern theory Advanced by Forman. Results and discussions: the present situations of the domestic and foreign river floodplain'ecological and landscape reconstruction were summarized, and the research insufficiency and present's research key were pointed out too. Then the latent ecosystem service functions and values of the Zhengzhou Yellow River Floodplain were appraised:the ecological functions and values, including the biodiversity maintenance function, the climate adjustment and the water source self-restraint functions, the soil maintenance and the environment purification functions, the disaster prevention function; economic production functions and values; social functions and values, including scientific research and education functions, traveling and inheritance values. The landscape structure of the Yellow River Floodplain was constructed. At last the guiding ideology was determined, and the forestry system planning was carried on, the forestry system was divided into eight parts:protection-water and soil conservation-cushion forests, protection-water and soil conservation-amusement and rest-biodiversity protective forests, view and admire-amusement and rest-education-idioplasm resources forests, amusement and rest-leisure-view and admire forests, economical-view and admire-amusement and rest forests, view and admire-amusement and rest-education-biodiversity protective forests. The agricultural system planning was carried on, and the guiding ideology was determined, the agricultural system was divided into four parts:the Zhengzhou agriculture science and technology demonstration garden, Feng Le-kui garden, agricultural demonstration garden along the river, agricultural park. the traveling system planning was carried on, the guiding ideology was determined, and the system was divided into six parts:The ecological sightseeing trip, the leisure travel or on vacation, the popular science and inspection traveling, the agriculture sightseeing trip, the popular science inspection traveling, the agriculture sightseeing trip, the movement leisure traveling, the cultural leisure traveling. The wetland nature protection area and the wetland park were constructed.
