过去关于水陆关系的研究主要视角聚焦在水陆之间的资源补贴上，但缺乏生物多样性水陆空间关系在流域整体格局的研究。了解流域水陆生物多样性整体格局是水陆补贴研究的前提，也是流域生态学的集合生态系统发展方向要求，可以揭示流域的整体功能。水生昆虫是一个功能多样的类群，其流域分布又受到水体和分水岭构成的流域环境梯度的影响。因此，本项目拟以水生昆虫作为对象，在滇西北苍山地区进行长期持续监测，开展流域单元内水生昆虫多样性的水陆整体分布格局、水陆分布的相互关系，以及基于流域整体多样性分布格局的视角探讨水生昆虫群落配置的驱动力等研究。本研究基于横断山脉的地貌特征，在集合群落配置理论研究上进行了视角创新，拓展了传统水陆相互关系研究的维度，研究结果对推动流域生态学的发展起着重要作用。申请人及所在团队对滇西北地区水生昆虫有研究基础，对苍山地区溪流中水生昆虫的季节性动态数据已收集多年。

Previously, many studies have been conducted on the amphibious spatial relationship in variant taxa, however, lots of them focused on resources compensation in between water-land system, rare studies concerned the integrative patterns of biodiversity throughout watershed. Understanding the watershed amphibious spatial biodiversity pattern with full knowledge of amphibious resources compensation is the prerequisite and demand of development of meta-ecosystem with watershed ecology perspective, that provides a measure to reveal the functioning processes of a watershed. Aquatic insect is a group with variant ecological functions, most of them hold the strong dispersal capacity, the watershed distribution of aquatic insect is strongly influenced by the environmental gradient which is caused by the relationship between waterbodies and divides. Therefore, this study focuses on the integrative distribution pattern of aquatic insect biodiversity in amphibious spatial within watershed unit, and long-term continuous monitoring will be conducted in Cangshan Mountain in northwest Yunnan province. The key research contents including the effects of watershed divide on biodiversity distribution, vertical distribution of biodiversity within the watershed, amphibious spatial relationship of biodiversity. Trying to uncover the driving forces for the aquatic insect community formation with an integrative perspective of watershed. This study is a pioneer work which provides a new aspect of meta-community theory, extent the traditional research of amphibious spatial relationship, based on the topographic features of the Hengduanshan Mountains, the results of this study will reinforce the development of watershed ecology. The applicant and his team be equipped to study on aquatic insects in northwest Yunnan province, and had seasonal collected aquatic insects in streams in Cangshan Mountain for many years.
