| 摘 要： | 为了客观定量地监测与评估2006年夏季发生在我国川渝地区历史罕见的高温干旱对生态环境造成的影响，利用所创建的基于植被第一性生产力（NPP）估算的生态气象评价指数（EMI）模型，计算分析了6-8月川渝地区的生态气象评价指数及其等级。结果表明，川渝地区生态气象评价指数较常年同期偏低，其中四川33％、重庆43％的地区生态气象等级较差或很差。两地6月与8月生态气象等级较差的范围大，7月较小。各生态系统中，城镇等生态气象等级很差；农田、草灌等明显偏差；林地生态气象等级正常稍差。干旱造成的生态影响多数是可逆的，气象条件得到改善后可以恢复。因此，应采取适当措施恢复各类生态系统的服务功能，把灾害带来的损失降到最低。

| Abstract: | In order to monitor and evaluate objectively the impact of rare high temperature and drought on meteorologically-driven ecological environment occurring in Sichuan-Chongqing area in summer 2006.The meteorologically-driven ecological assessment index (EMI) model which was established based on the estimate of the net primary productivity (NPP) was used to calculate the EMI and its rank. The results show that the ecological and meteorological conditions were worse than the perennial summer in the region of Sichuan and Chongqing, and the EMI rank was worse or very worse in 33% areas of Sichuan Province and 43% areas of Chongqing City. The worse area of EMI of Sichuan and Chongqing in June and August was larger than that in July. In different ecosystems, the EMI of city and town was very worse, and the EMI of cropland and grass and shrub land was obviously worse, but the EMI of woodland was nearly normal. The ecological effect of drought is reversible, and it can be restored after the weather condition improved the ecosystems service function. Therefore the effective measures should be adopted to restore the ecosystem service functions and to decrease greatly the various of the loss. |
