青藏高原地区土壤有机质数据（1979-1985）

数据包含青藏高原地区的土壤有机质数据，空间分辨率为1km*1km，时间覆盖范围为1979-1985年。数据来源是基于第二次土壤普查数据生成的土壤碳含量。土壤有机质主要来源于植物、动物及微生物残体，其中高等植物为主要来源。原始土壤中最早出现在母质中的有机体是微生物。随着生物的进化和成土过程的发展，动物、植物残体及其分泌物就成为土壤有机质的基本来源。数据对于分析青藏高原的生态环境以及衡量区域土壤特征具有重要意义。

This dataset contains soil organic matter data for the Qinghai-Tibet Plateau, with a spatial resolution of 1 km × 1 km and a temporal coverage from 1979 to 1985. The data is derived from soil carbon content generated based on the Second National Soil Survey dataset. Soil organic matter mainly originates from the residues of plants, animals and microorganisms, with higher plants being the primary source. The earliest organisms that appeared in the parent material of primitive soil are microorganisms. With the evolution of organisms and the development of soil formation processes, the residues and secretions of animals and plants have become the basic sources of soil organic matter. This dataset is of great significance for analyzing the ecological environment of the Qinghai-Tibet Plateau and evaluating regional soil characteristics.
