The Study On Sightseeing Orchard Ecosystem Service Function Evaluation Based On Landscape Pattern Analysis

Sightseeing orchard is a kind of modern agricultural production model which is given priority to the plant production. It is not only provide people for various material supply service, but also supply people's spiritual needs. In order to explore sightseeing orchard landscape elements, and its role in improving urban environment (the evaluation of ecosystem services assessment), this article study Changsong sightseeing orchard at Baihe town of Longquanyi district in Chengdu, using the ecology principle and landscape pattern to evaluate ecosystem service function of the related research and evaluation. Thus obtained the following results:(1) The understanding and awareness for "sightseeing"Sightseeing is a social behavior participating within a certain time and visit specific geographical landscape to meet their spiritual needs.(2) The characteristics of the landscape pattern in the study areaIn the study area landscape pattern is:consists of residential buildings, farmland and unused land of "patches" set in the orchard and forest land constitute the "matrix", roads and water system as a "corridor" connection among them.(3) The division of ecological system and its service function in the study areaSightseeing orchard ecosystems in the study area is composed by the orchard ecosystems, forest ecosystem, farmland ecosystem, water ecosystem, and desert ecosystem.Ecosystem services are divided into two levels. Level 1 including:supply services, Regulating services, support services, cultural services and social security service five categories. Level 2 segment including:food production, the production of raw materials, water supply, gas adjustment, climate regulation, hydrology regulation, purifying environment, and keep the soil, to maintain nutrient cycling, maintaining biodiversity, providing aesthetic landscape, tourism and leisure, old-age security, employment guarantee which are 14 classes.(4) Ecosystem service function value assessment in the study areaThe value of Longquan Changsong sightseeing orchard ecosystem service function reached 2.1288507 billion yuan. Supply services is about 7.08% and the total value of 150.7281 million yuan. Then, regulating services accounted for about 7.18% which total value accounted 152.8246 million yuan. Support services accounted for about 5.33% which is 113.4 million yuan. Cultural services is about 78.88% this is the largest amount of 1.6792139 billion yuan. Last, the social security function value accounts for about 1.53% and its total value will be32.6841 million.(5) Suggestions for the sustainable development of sightseeing orchard in Longquanyi districtThrough studies suggest that Longquanyi District in order to achieve healthy and stable development of sightseeing orchard should be done from the following three aspects to further improve:Maintain and improve the existing ecological system, then, diversify the business model, and improve service quality for the orchard. Unified planning of established the orchard, and specialized of standardized management.
