| 摘 要： | 以扎龙湿地中出现的盐碱化趋势分析来说明在自然因素和人为干扰尤其是人为活动的干扰下，扎龙湿地中出现了盐碱化加强的趋势，这不仅仅表现在盐碱地的总体数量的增加，而且表现在盐碱地结构中中度和重度盐碱地比例的增加；盐碱地的主要转入类型为草甸草原；从空间分布上来看也有从实验区向核心区扩散的趋势。图3，表3，参14。 |

| Abstract: | This paper mainly introduced the application of Remote Sensing technology, Geographic Information System and Global Positioning System in wetland monitor and management. As a case of study, there was much landscape of alkaline land in Zhalong wetland, we can analyze the basification trend in order to show the strong advantage of 3S in wetland monitor and management. As a result, quantity of alkaline land increased, and the basiflcation degree became more serious. A lot of grass land transformed alkaline land, and alkaline land began appearing in core area. |
