黄土高原关键带土壤水文过程研究进展与展望OA北大核心CSTPCD

Research progress and prospect of soil hydrological processes in critical zone of the Loess Plateau

中文摘要英文摘要

地球关键带是 21 世纪地球科学的前沿和重点领域之一.黄土约占全球陆地面积的 10%,中国的黄土高原是典型的地球关键带之一.土壤水文过程驱动着黄土高原关键带不同尺度的系列生物地球化学循环过程,决定土壤-植被-大气连续体的演化方向与可持续性.基于地球关键带"4M"研究框架,综述了黄土高原关键带土壤水文过程研究的热点与前沿,梳理了不同尺度土壤水文过程的观测方法与技术、模型模拟与填图、深层土壤干化管理等研究进展;在此基础上,围绕黄土高原关键带土壤水资源优化利用与生态系统服务功能提升,提出了全球气候变化和大规模人类活动共同影响下黄土高原关键带土壤水文过程的优化管理对策和建议,展望了黄土高原关键带土壤水文过程研究的未来趋势.以期深化黄土高原关键带研究的科学认知,促进地球关键带科学的发展,为黄土高原自然资源优化管理、山水林田湖草系统治理提供科学参考.

The Earth Critical Zone(CZ)is one of the frontiers and key fields of earth science in the 21st century.Loess accounts for about 10%of the global land area,and the Chinese Loess Plateau(CLP)is one of the typical Loess CZs.Soil hydrological processes drive a series of biogeochemical cycles at different scales in the CLP-CZ and determine the evolution direction and sustainability of the soil-vegetation-atmosphere continuum.Based on the"4M"research framework of the CZ science,we summarized the hot spots and frontiers of soil hydrological processes in the CLP-CZ,and then reviewed the research progresses of soil hydrological processes at different scales,including the observation methods and techniques,model simulation and mapping,and deep soil drying management.Based on this,focusing on the optimal utilization of soil water resources and the improvement of ecosystem service function in the CLP-CZ,the countermeasures and suggestions for the optimal management of soil hydrological processes in the CLP-CZ under the joint impact of global climate change and intense human activities were put forward,and the future trend of soil hydrological processes in the CLP-CZ was forecasted.A good understanding of this information is helpful to deepen the scientific understanding of the CLP-CZ research,promote the development of the CZs science,and provide scientific reference for the CLP natural resources optimization and mountains,rivers,forests,farmlands,lakes,and grasslands ecosystems management.
