| Abstract |
Why do we implement ecological engineering? Why do we reduce concrete? For the recent decades, people have used a large portion of concrete to build many constructions, and most of them protect our living circumstance; however, the
concrete constructions also cover a large portion of land that also decreases the living environment of many living things. Luckily, under the trend of ecological protection, the Pu-zih Stream has gradually been dredged by means ecological engineering. Nevertheless, we have to ask whether the ecological engineering can off what kind of functions to protect the environment.
The reconstruction of the Pu-zih Stream is to prevent the floods and dangers,
which can effectively protect peopleˇ¦s lives and property. At the early phrase, ˇ¨the
soil dikeˇ¨ was the best way used in ecological engineering. However, for the sake of safety, ˇ§the soil dikesˇ¨ which was built first has mainly focused on ecological and usable aspects. How to keep a balance between ecological and usable aspects is the
Purpose of this ecological engineering.
Another key point of the research is to fix the pollution of the Pu-zih stream. It is the first step to ensure a variety of ecological environments because the result of dealing with pollution will directly affect to their ecological protection. The government used to focus on the construction of transportation and ignored sewerage system. Now, in the Pu-zih stream the first priority and need have a long-term plan is to deal with the sewage of 75% from family and 13% from animal husbandry. |
