摘要/Abstract

摘要： 在干旱荒漠区，降水呈现强烈的脉动特征（即降水频率、强度及数量的高度变异性），降水脉动变化对荒漠土壤动物的分布格局有显著影响。目前对降水脉动如何影响和调控荒漠土壤动物分布格局形成与维持的生态机制的认识非常有限。因此，深入开展干旱荒漠区降水脉动变化对土壤动物群落分布及多样性影响研究具有重要的科学意义。本文围绕“降水脉动驱动资源脉动影响土壤动物食物网结构”这一核心问题，重点从自然降水变化、冬季降雪变化和夏季降雨变化等方面对国内外的研究动态及最新研究进展做比较系统的评述。在此基础上，探索干旱荒漠生态系统响应降水变化研究中应重点关注的几个前沿科学问题，这可为中国干旱荒漠生态系统生物多样性保护管理提供科学依据，促进荒漠生态系统生物多样性保育理论、资源脉动生态学理论和研究方法的发展。

Abstract: In the arid desert areas, natural precipitation has a strong characteristic of pulse, namely strong variations in the frequency, intensity and quantity of precipitation. This precipitation pulse may have an important impact on the distribution pattern of soil animals. However, our knowledge on the influence of precipitation pulse on the distribution, composition and diversity of soil animal communities remains limited Hence, there is a need for a more thorough exploration of the mechanisms underlying how precipitation pulses affect the distribution pattern of soil animals at different taxonomic and trophic levels. This paper gives an overview of advances in the study of the precipitation pulse drive resource pulse affect the soil animal food web structure, which is the core issue, with a focus on the natural precipitation, winter snow and summer rainfall changes in the domestic and international research developments and the latest progress of the study to compare the system of review; on this basis, exploring arid desert ecosystem response precipitation change research in the focus on and study of several cutting-edge scientific issues several issues, which can be to our arid desert ecosystems biological diversity conservation and management provide a scientific basis and promote desert ecosystem biodiversity theory, resource pulse ecology theory and research methods.
