青海省都兰县草地类型面积、载畜量统计数据（1988，2012）

该数据集记录了1988年，2012年度青海省都兰县草地类型面积、载畜量统计数据，数据按照草地类组型代号分类统计，如：Ⅰ代表高寒干草原类、Ⅱ代表山地干草原类、Ⅲ代表高寒荒漠类、B代表中禾草组、J代表灌木组等，具体的草地组类型代号及其对应的含义见数据集中的“青海省草地类组型代号说明.pdf”。数据整理自青海省草原总站与1988年和2012年发布的《青海省草地资源统计册》。数据集包含3个数据表，分别为：都兰县草地类型面积.载畜量统计数据（1988），都兰县草地类型面积、载畜量统计数据 （2012）和青海省草地类组型代号说明。数据表结构相似。例如都兰县草地类型面积、载畜量统计数据 （2012）表共有8个字段：
字段1：类型代号
字段2：草地类型名称
字段3：草地面积
字段4：草地可利用面积
字段5：平均单产鲜草
字段6：平均单产可食鲜草
字段7：载畜量
字段8：草地型等级

This dataset records the statistical data of grassland type area and livestock carrying capacity in Dulan County, Qinghai Province for 1988 and 2012. The data is classified and counted based on grassland group type codes. For example, code Ⅰ represents alpine dry grassland type, Ⅱ represents mountain dry grassland type, Ⅲ represents alpine desert type, B represents medium graminoid group, J represents shrub group, etc. The specific meanings of all grassland group type codes are detailed in the document "Instructions for Grassland Group Type Codes of Qinghai Province.pdf" included in the dataset.

The data is collated from the *Statistical Book of Grassland Resources of Qinghai Province* released by the Qinghai Provincial Grassland Station in 1988 and 2012. The dataset contains 3 data tables, namely: Statistical Data of Grassland Type Area and Livestock Carrying Capacity in Dulan County (1988), Statistical Data of Grassland Type Area and Livestock Carrying Capacity in Dulan County (2012), and Instructions for Grassland Group Type Codes of Qinghai Province. The structures of these data tables are similar. Taking the table "Statistical Data of Grassland Type Area and Livestock Carrying Capacity in Dulan County (2012)" as an example, it has a total of 8 fields:
1. Type Code
2. Grassland Type Name
3. Grassland Area
4. Usable Grassland Area
5. Average Fresh Grass Yield per Unit
6. Average Edible Fresh Grass Yield per Unit
7. Livestock Carrying Capacity
8. Grassland Type Grade
