()
摘要:
选取自然性、多样性、代表性、稀有性、生态脆弱性、面积适宜性、人类威胁等指标对河南小秦岭自然保护区森林生态系统进行评价.运用层次分析法对生态评价因子进行等级化处理,确定各评价指标的权重,计算各生态评价因子的评价指数(CEI),得出的综合评价指数为0.8422,表明小秦岭自然保护区森林生态系统的生态质量较好, 保护价值较高.此外,还就保护区目前所面临的问题提出了相应的建议.

Ecological evaluation of the forest ecosystems in Henan Xiaoqinling nature reserve
()
Abstract:
In this thesis,indices such as naturalness,diversity,representativeness,rarity,ecological fragility,suitability of area and human impacts were selected to evaluate the ecological quality of Henan Xiaoqinling nature reserve.The value of each index was determined by the evaluation system,and the weight percentage was decided by analytical hierarchy process(AHP).The composite evaluation index(CEI) was figured out as 0.8422,suggesting that the ecological quality of the nature reserve could be relatively good,and the protection value should be quite high.Finally,the problems facing the reserve at present were analyzed and the corresponding proposals were put forward.
Key words:  nature reserve,forest ecosystem,ecological evaluation,AHP
