Ecosystem health evaluation for Shawan forest in middle part of tianshan mountain in Xinjiang
-
Abstract
【Objective】 Taking Shawan Forest Farm in the middle of Tianshan Mountain as the research area, this project aims to assess the forest ecosystem health in Shawan forest farm by extracting the index factors from remote sensing data to measure the health of forest ecosystem in terms of four aspects: ecosystem service function, landscape ecological structure and function, terrain factor, physiological and ecological status. 【Method】 Using the data of remote sensing and forest resources date in Xinjiang, through the correlation analysis of the indicators and influence degree of each factor on the health of the forest ecosystem, the entropy weight method and the comprehensive evaluation method were used to quantitatively evaluate the health of the forest ecosystem. 【Result】 The results showed that the index of ecosystem health was 0.12-0.59, among which the average index of coniferous forest landscape, broadleaf forest landscape, spare woodland landscape, shrubbery landscape, nursery landscape, afforested barren hills, non-forestland were 0.59, 0.56, 0.36, 0.41, 0.12, 0.53 and 0.48. 【Conclusion】 A comprehensive method for assessing the forest ecosystem health is established, which can provide theory and method for forest health maintenance and sustainable management in the central Tianshan forest region of Xinjiang.
