title: Soil Quality Evaluation Dataset of Northeast Corn Belt (2013)
title: 东北玉米带土壤质量评价数据集（2013年）

description: a. Data content (data file/table name, including observation indicators)
This data includes the Northeast Corn Belt cultivated land soil quality evaluation dataset (full dataset TDS and minimum dataset MDS), reflecting the characteristic indicators of soil quality, environmental factors, agricultural management, and the relationship between soil quality, providing data support for farmland protection, soil remediation, and other aspects.
b. Construction purpose
Soil quality assessment has become a fundamental work for sustainable agricultural development. Understanding the soil quality of cultivated land in the Northeast corn belt and improving agricultural efficiency can provide valuable foundations for alleviating the supply and marketing contradictions in China's corn production. At the same time, research is also of great significance for ensuring national food security and promoting the development of animal husbandry and corn processing industry.
c. Service target
It can widely serve scientific researchers in related disciplines such as farmland protection and soil quality assessment.
d. Time range of data
2013
e. The spatial scope of data
Changchun City, Shuangyang District, Nongan County, Dehui City, Jiutai District, Yushu County, Gongzhuling, Lishu, and Yitong County in Jilin Province
f. Projection method of data
Projected Coordinate System：Krasovsky_1940_Albers
Geographic Coordinate System：GCS_Krasovsky_1940
g. The disciplinary scope of data
Geography and Ecology
h. Quantity of data
The total data volume is about 194MB
