Landscape Pattern Analysis And Ecosystem Health Assessment For Changchun Lianhuashan Ecological Tourism And Resorts Zone

Landscape Pattern Analysis and Ecosystem Health Assessment for Changchun Lianhuashan Ecological Tourism and Resorts ZoneChangchun Lianhuashan Ecological Tourism and Resorts Zone located east of Changchun. The south of this zone was Shuangyang and Jingyue District Economic Development Zone. The north was Donghu and Xinglongshan. The east was Shitoukoumen Reservoir. Some parts of the study area were in the drinking water source protection areas of Shitoukoumen reservoir. The major landscapes were farmlands and forests. Overall, the ecological environment of this area was good.Land use status has a decisive influence on the ecological environment. And it affected ecosystem health and socio-economic sustainable development in a larger scale. In this study, we analyzed the landscape pattern and assessed the ecosystem health of Changchun Lianhuashan Ecological Tourism and Resorts Zone under different land uses. The results could provide theoretical basis for local land use planning and development. At the same time, it had important practical significance for constructing the regional ecological environment, improving ecological environment and sustainable development of society.In this study, by reading relative materials, we summarized current research methods and selected proper analysis and evaluation methods. According to the actual situation, at the level of the patch type, we select patch density, patch area percentage of landscape, mean patch size, edge density, fractal dimension index as the calculation index. And at the landscape level, Shannon diversity index, Shannon evenness, landscape contagion index and landscape fragmentation index were selected to analyze the landscape pattern status. Meanwhile, based on the "pressure-state response" framework, we built of the evaluation system of regional ecological health. AHP method was used to determine the weight of each evaluation factor. After normalized, all factors were used to assess the comprehensive status of this area. Based on the grading standards, the results could be quantitated.The main conclusions of this study are as follows:First, in the study area, the largest landscape was farmland. It has absolute advantage and well connectivity. The features in the landscape play an important role in influencing regional material flow and energy flow. The formations of landscape structures were strongly influenced by human activities. This reflected the typical characteristics of landscape. All the landscape patch types were clustered in distribution.Second, the pattern of the area was still good. And the natural resources and conditions are better. Overall, the study area had stronger system activity, less external pressure, no unusual phenomena and well ecosystem functions. The system is still stable and sustainable. Ecosystem health of Changchun Lianhuashan Ecological Tourism and Resorts Zone was in the second grade. This rank is better. However, in the response structure, the result was relatively poor. This could be mainly due to the lower level of economic development.
