摘要

甘肃黄河流域是一个生态问题和发展问题交织在一起的自然-社会-经济复合生态系统, 其生态系统土壤保持服务是防止水土流失和推动高质量发展的重要保障。使用归一化植被指数、 土地利用产品MCD12Q1、 降水数据、 数字高程模型数据和土壤数据库HWSD v1.1, 运用修正通用土壤流失方程RUSLE, 计算得到了甘肃黄河流域的土壤保持服务年度数据集。该数据集, 空间范围为33°6′29″N - 40°0′6″N、 97°23′38″E -108°42′38″E, 时间跨度为2001 -2015年, 可为制定土壤保持服务措施提供科学依据, 也为评估生态安全和构建生态安全格局提供重要数据支撑。实体数据集获取网址为http: //www.ncdc.ac.cn/portal/metadata/a918f7ed-5988-44ea-80ad-ee14acab89aa.

Abstract

Gansu-Yellow River basin is a natural-social-economic complex ecosystem intertwined with ecological and development issues.Soil conservation service (SCS) is an important safeguard for preventing soil erosion and promoting high-quality development in this region.Combining with the Revised Universal Soil Loss Equation(RULSE), we obtained the annual SCS dataset for Gansu-Yellow River basin from the Standardized Vegetation Difference Vegetation Index, Land Cover Type product MCD12Q1, precipitation data, Digital Elevation Model data and the Harmonized World Soil Database version 1.1.The times span for this SCS dataset ranges from 2001 to 2015, with spatial coverage between 33°6′29″N -40°0′6″N and 97°23′38″E -108°42′38″E.This study offers a scientific basis for developing measures to improve SCS, and provides important data support for assessing ecological security and constructing ecological security pattern.The URL for obtaining the entity dataset is http: //www.ncdc.ac.cn/portal/metadata/a918f7ed-5988-44ea-80ad-ee14acab89aa.
