The study of Ningde East Lake National Wetland Park landscape resources constitute landscape ecological characteristics, ecological environmental capacity investigation, analysis and comprehensive evaluation, research including the Ningde the Donghu plant species resources survey, the number of characteristics and species diversity, wetland landscape characteristics, wetland environment quality spatial and temporal changes in wetland park resources quality, wetland ecological water demand and environmental capacity and wetland effectiveness of systems analysis and comprehensive study, the main results are as follows: (1) Ningde East Lake National Wetland Park community analysis, showed that the Ningde East Lake National Wetland Park to artificial vegetation were found in the plant species, 81 species belonging to 50 families and 65 genera, including: five kinds of ferns, belonging to four families, 5 genera; gymnosperms 2 families, 2 genera and 2 species; angiosperm genera and 44 families, 58 genera and 74 species. The species of the tree layer trees, eucalyptus, camphor tree, Metasequoia, fake betel nut, Casuarina, Begonia, myrobalan plum, privet, India rubber tree and other species. Low shrub layer species diversity, the major species of nandina, peach, fake forsythia, small wax, oleander, red pompon, plantain, Yinhua. Herbaceous layer is vigorous growth throughout the community, both in the number and position of absolute dominance on the cover, is mainly composed of species of reed, wormwood, Patrinia, smartweed, Alternanthera philoxeroides, willow Ruo, thistle, oil of Mans, Peng Qiju, sedges. (2) analysis of Ningde East Lake Wetland Park landscape characteristics, the results show that the largest reservoirs and intertidal mud beach, its proportion was 31% and 27%, respectively, show that the structure of the reservoir, and intertidal mud beach on the entire landscape and diverse sexual proportion of heavier role in Ningde East Lake Wetland Park landscape types, intertidal the saltwater marsh fragmentation, but also the most complex patch shape the landscape type. (3) the study of the temporal and spatial variation of Ningde East Lake Wetland Park environmental quality and its driving force, the results show that, regardless of the water quality of the lake, or Ningde East Lake wetlands water quality have shown varying degrees of pollution, which BOD5, COD and NH3-N three the most serious kinds of pollutants, the pollution index reached 15.3,8.2 and 8.1, between 2003-2009, Ningde the Donghu wetland water level of environmental pollution weakening trend. South interpersonal Creek Ningde Donghu a major source of pollutants in wetlands, and Jinxi rivers Ningde East Lake wetland ecological environment quality play to improve. Ningde East Lake Wetland Park environmental quality change in the driving force of the analysis showed that the proportion of primary industry, secondary and tertiary industries output value play a decisive role in the quality of the water environment of the wetland ecosystem. (4) Analysis and Evaluation of Ningde East Lake Wetland Park resources, results, the Fujian Ningde the Donghu travel resources quality assessment score of 76 points. Meet the excellent standard level scenic resources of the Coastal Wetland Park rating, the higher the value of its resources and tourism value, should ensure that its precondition for sustainable development, scientific and rational development and utilization. (5) Ningde East Lake Wetland Park ecological water demand study, the results show that, Ningde, East Lake Wetland Park optimal, medium and minimum ecological environment water demand sum of 1421.3 × 104m3, 1015.3 × 104m3 and 609.35 × 104m3. Optimal, medium and minimum ecological water demand accounted for the proportion of the effective capacity of 124 .. 13%, 88.67% and 53.22%, respectively, but decreases with the effective storage capacity, while the serious pollution of water resources, Ningde Donghu wetlands water resources it is difficult from the water meet ecological water demand and water quality in two aspects. (6) research on the Ningde environmental capacity of the East Lake Wetland Park and the tourists capacity, results showed that the Park to the building is basically completed, the date of the environmental capacity of 3914 passengers / d, an annual environmental capacity of 1.2 million passengers. Saturated day environmental capacity expansion of 2 times daily environmental capacity for 7828 passengers / d. Park Day visitors capacity of 2951 passengers / d; annual capacity of 903,000 passengers / a tourists. (7) Ningde East Lake Wetland Park-effectiveness analysis, that based eco-tourism, financial natural and cultural landscape in one, wetland plants, water, birds and other landscape for relying, wetland culture, farming culture fisheries culture as connotation, to wetland ecological protection for the purpose, through rational distribution, science partition, careful planning, and local conditions to set a variety of tourism infrastructure facilities, laid the best swim Road, rational organization of tours, the Park Construction scientific advance and operability the park is completed science education, wetlands tourism, quality education, leisure, scientific investigation as one of the multi-function Wetland Park. The Park Construction significant ecological and social benefits at the same time, certain economic benefits. Provide follow-on funding guarantee for the sustainable development of the park, the effective protection of wetland resources.
