摘要
湿地是富有生物多样性、多功能的生态系统 .无论从经济学还是生态学的角度看它都是最具有价值和生产力的生态系统 .目前湿地面临着污染、围垦、过度开发的威胁 ,湿地资源日益减少 ,物种和遗传基因多样性损失惨重 ,生产力下降 ,使湿地及其生物多样性的保护显得更为紧迫和重要 .
Wetland abounds in biodiversity and multi-functional ecosystem,which is the best ecosystem possessing value and productivity both from the angles of economics and ecology.At present,wetland is confronted with the threat of pollution,enclosing tideland for cultivation and over-exploitation. The species and transgenic diversity have been seriously damaged and productivity has been lowered. All this reveals that wetland protection and biodiversity seems to be more urgent and important.
