Abstract
Climate Change impacts not only on individual situation but on short-term variation and on long-term gradually changes. This kind characteristic should adopt the suitable environmental management with long-term formulation and short-term operation in sure keeping environmental sustainability as social economy developing using environmental resource. In this article, the climate change assessment has been combined to set up an early warning system for a river, and focus on analyzing climate change impacts on water quality and stream assimilative capacity. The issue of warning period is also discussed, and furthermore, the adaptative strategies are provided and evaluated.
However, there is a problem for establishing an early warning system that estimate future climate changes would be faced with high uncertainty. In general, take estimations would use global scale GCMs data but too rough-cut for estimating a smaller region, such a stream area. In order to get over the problem, the statistic downscaling model (SDSM) has been used for regional analysis and the data is applied for Touchen River in North Taiwan. The result shows that after downscaling can display regional characteristics reasonably.
Farther, the data analysis also shows that in arid period, the concentration of BOD is growing worse. The BOD assimilative capacity of a river is confronted by decreasing. For understanding when will suffer the risk, not only climate change assessment but also local evolution will include to establish an early warning indicator (EWI) for analyzing the warning period, and then, to estimate the optimal strategy and when should take action. Furthermore, the acting warning will be alerted.
For sustainable development, both bioenvironmental sustainability and social economy development are important. How to find a compromising point between human development and natural conservation is crucial. But climate changes impacts throw down the gage to our resource. To avoid the impacts, by impacts assessment we establish an early warning system for early warning what risk is, when risk will happen, and how we choose the optimal strategy for planning the course of management. Hopefully by setting up the framework of early warning system can defend stream area form impacts damaging and in sure the sustainable development.
