摘要
以八仙山国家级自然保护区为例,获取了其在1992年和2002年的生态系统信息数据,分析该保护区10年间生态系统健康的变化。研究结果表明:研究期间保护区生态系统健康状况变化很小,仅略有降低;活力及弹性值小幅上升。说明保护区整体植被良好,部分地区经过开发变为无植被地对生态系统健康影响很大。
Taking Baxian national nature reserve as an example, the paper obtains the information data of the ecosystem in 1992 and 2002 respectively to analyze the change of ecosystem health of this reserve over 10 years. The result indicates that there is a little change （a bit decreasing） in ecosystem health condition in the period of the study, but a little bit rising in elasticity and vitality, both of which explain that the whole vegetation in the reserve preserves well, but partial area where has undergone overexploitation to be changed into bare area without any vegetation has great impact on the ecosystem health.
