Biological Integrity Evaluation of Liaohe River
摘要
Abstract
The biological integrity evaluation of Liaohe River, selecting evaluation factors due to its own characters, is aimed to provide reference for the comprehen sive planning and management. The results of evaluation of biological integrity of Liaohe River were drawn by comparing the methods and indices of China and abroad, selecting the factors from three aspects, including the ecosystem composition, energy flow and river services. Nine indices from 20 candidate indices were selected by calculating the mean value and standard deviation of document number assignment, including fragmentation of patch types, landscape diversity index, habitat complexity, indicative species retention rate, rare species retention rate, index of biological integrity of fish, index of biological integrity of zoo benthos, interference index of aquatic habitat and hazard rating of invasive species. The comprehensive evaluation method was used to evaluate the biological integrity in 2012 and 2016. The result showed that the biological integrity of the Liaohe River protected area in 2016 was Class II (good), with the integrity assessment of Class I (excellent) in Fudedian and Sanhetun, Class II in Zhuershan, Mahushan and Shuguang bridge, Class III (general) in Shuanganqiao, Shifosi, Hongmiaozi and Dazhang,and Class IV (poor) in Xingan.;The biological integrity of the Liaohe River protected area in 2012 was Class III and Class IV, with the integrity assessment of Class III in Fudedian, Sanhetun, Shuanganqiao and Shuguang bridge, Class IV in Zhuershan, Shifosi, Mahushan, Hongmiaozi and Dazhang, and Class V(very poor) in Xingan. The evaluation results could be referred for researchers and managers to identify the health status and carry out ecological restoration work.关键词
