Quality Evaluation Of Wetland Landscape Of Apengjiang In Chongqing

In this paper, Apengjiang National Wetland Park as an example, under the guidance of the theory of landscape ecology, wetland landscape from start focusing on Apengjiang wetland landscape quality evaluation. According to science, simplicity, operability, adaptability, systematic, comparable and combination of qualitative and quantitative indicators of the basic principles of selection to properly evaluate the wetland landscape indicators, according to the principle of purpose, taking into account the principle of scientific principle, feasibility, operability principles and system integrity principle, through brainstorming, Delphi method, regression-based methods such as screening indicators for the selected indicators screening, wetland landscape quality evaluation system framework. Then, AHP is used to judgment matrix to determine the weight of each index. AHP, expert scoring method, according to the Apengjiang actual situation of wetlands, wetlands invited experts on indicators scoring. According to the scores of individual indicators and weights, calculated Apengjiang wetland landscape overall quality score. The main contents and results are summarized below.1. According to brainstorming, Delphi method, regression-based indicators screening method are three ways to get through the four screening wetland landscape quality evaluation system framework, determine an5first-grade assessment indicators,15secondary indicators, namely:①scientific value (the value of research and teaching, genetic diversity, species diversity),②overall outlook (structural complexity, harmony with the surrounding environment, location),③science propaganda value (publicity coverage, publicity times, promotional venues),④historical and cultural value (historical figures, historical events, cultural heritage),⑤aesthetic value (deep degree of openness, visual diversity). Then AHP is used to determine the weight of each index.2. AHP, expert scoring method, according to the Apengjiang actual situation of wetlands, wetland experts invited, after three scoring, scores obtained for each indicator are:research and teaching value8.2, genetic diversity of8.8,8.4species diversity, structural complexity8.2,7.6coordination with the surrounding environment, geographic conditions8.4, range6.9propaganda, propaganda times8.2, 7.6promotional venues, historical figures8.1,6.5historical events, cultural heritage7.8, deep degree7.8,7.9openness, visual diversity8.2. According to the scores of individual indicators and weights, calculated Apengjiang Wetland landscape quality overall score of8.17, and the individual assessment score values were greater than60%of the total score, draw Apengjiang wetlands rating of excellent quality.3. According to the results, this paper presents several management measures, including the development of park management regulations, strengthen the construction of transport facilities, and coordinate the relationship between the park and the surrounding community, increase publicity efforts and the strengthening of the park within the park construction and protection of forest resources etc., in order to provide reference for the healthy development of the park.
