一、 針對目前雁鴨危害農作物問題嚴重之秀姑巒溪流域探討其形成雁鴨 危害之可能原因。
No matter overseas or our country, something, which we can except, is the problem of the wild life harm the crops never stop happen.
Simultaneously, people need the land become strongly. It would be break original habitat. Let the problem keep going.
The migrating ducks product the harmful problem that experience for several decade in overseas. The government and the authorities start to attach importance to the cause.
Due to such question a deal of the beginning in Taiwan, only use the ways that is deporting, killing with poison, and catching …etc face the problem. It couldn’t solve and reduce the harm fundamentally.
So, this study advocated the problem of ducks harm should be manage systematically and integrate into the organization.
First, developing to revive the habitat for ducks reproduction and subsistence. Second, reducing the behavior of harm from ducks processing the technique of prevention and cure, decreasing the crops attract the ducks and proceeding the management of farm. Finally, it is necessary to control the number of ducks in the meanwhile to estimate the extent of injury and assess the system of the prophylaxis and treatment for monitoring the problem long time.
At the same time, one of the natural resources to use is ducks. For example, proceeding the project of tourism…etc. Today, to draft an entire management is the important for the wild animal harm of crops.
The purpose of this research:
1. It is aimed at the extent of injury from ducks in Hsuikuluan Basin and to probe into the reason and how to form.
2. Drafting the entire and whole management to solve the problem of ducks harm the crops. It’s include to understand the possible reason cause to harm paddy rice in Hsuikuluan Basin.
3. Aspect of harm of prevention and treatment, we use the three kinds of pesticide to take the test for the pesticide affection to cope with ducks And to analysis the capital and the benefit by repellents.
By the way of this study to find out the issue of ducks harm the paddy rice, and provide a synthetic and entire prevention and treatment system. The goal is recycling perpetually, reducing the harm from ducks, and keep the number of ducks population to be good for ecological balance, then use this resource further.
According to we know that the result of investigation and the records that the main reasons of ducks harm the crops may be the environment changed and habitat decreased in Hsuikuluan Basin.
In the test of repellents, especially Phorate are the most effective. We can consider following the farmer’s way to operate capital and improve to be the useful method. Using the low capital to do the most effective way.
To solve the problem can’t use only one way, and it needs to combine all the projects and consider synthetically which can or not. The most important to do is to locate the monitored and appraised system and make sure perniciousness that can be monitored.
Further this managerial system needs a large-scale science. It includes biology, ecology, economics, and chemistry…Etc.A lot of professional experts is necessary to develop an entire system of the harm.
