材料一 中国是世界上遭受反倾销最大的受害国。据有关部门估算，中国出口产品遭受国外反倾销每年平均损失800多亿元人民币，并且导致大量相关企业人员下岗。随着中国成为第三世界贸易大国，未来20年将是中国企业应诉国外反倾销的高峰期。详见下图。

材料二  2008年4约9日，商务部副部长高虎城在出席“2008国际贸易形势分析会”时表示，今年我国面对的贸易摩擦的形势依然会非常严峻。“世界经济增速的放缓和不景气将导致国际贸易保护的加剧和贸易争端的增多，这基本上是个规律。”一季度的贸易摩擦形势初步佐证这一观点。截至3月底，共有八个国家和地区对我国发起17起反倾销、反补贴调查，涉案金额达20亿美元。我国还遭遇了美国“337调查”5起，案件数量和涉案金额都有大幅度的增长。 　

请结合上述材料，说明我国应怎样利用世贸组织的争端解决机制维护自己权益？
