探究外来种的分布和扩散规律是入侵生态学的核心研究内容之一，开展相关研究对保障国家生态安全具有重要意义。随着气候变化以及人类活动对环境的改变，一些外来鸟种在我国陆续出现，并在局部地区开始扩散，钳嘴鹳便是典型代表。该物种为热带鸟类，专性捕食螺蚌类，主要分布于东南亚和南亚的低海拔平原地区。自2006年首次在我国出现以来，已迅速扩散至云南、贵州、广西等省份，并在局部地区成为优势鸟种。在增加地区生物多样性的同时又表现出一定的"入侵性"特点，如爆发式扩张、排挤本地物种等。由于缺乏研究支撑，目前对于其"利弊"仍存在较大争议。因此对钳嘴鹳开展相关系统研究就极为迫切。本研究拟采用经典的野外调查方法以及卫星跟踪等新技术，掌握钳嘴鹳的种群数量、分布现状、生态需求、迁移（或迁徙）习性等，并利用"3S"技术构建钳嘴鹳的分布模型，阐明其分布机制并对其未来扩散趋势做出预测，从而为政府部门下一步制定管理计划提供科学依据。

Exploring the distribution and expanding pattern of alien species is one of the key area of invasive ecology.Carrying out related research is essential to protect national ecological safety. In recent years, the climate change and human activities are reshaping the distribution of animals. some exotic bird firstly appeared in China, and began to spread quickly. The Asian Openbill mainly occured in lowland plain of South Asia and Southeast Asia. In 2006, this bird firstly appeared in China, up to now, it has spread to Yunnan, Guizhou and Guangxi Province. This bird increased the local biodiversity. On the other hand, the rapid expansion also threaten the local species, e.g. cranes, storks and egrets. There is an arguement if it is good or bad to local biodiversity . So it is urgent to carry out reseach on the Asian Openbill. This study intends to use classical field survey methods and satellite tracking technology to study the population dynamics, distribution pattern, ecological demand and migration habit of Asian Openbill. We also model the distribution pattern of Asian Openbill and predict its potential distribution areas using GIS, Rs, and GPS technology. Our aim is to provide scientific proof for the directorial department to make management measures.
