青海省西宁市区草地类型面积、载畜量统计数据（1988，2012）

该数据集记录了1988年，2012年度青海省西宁市区草地类型面积、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：青海省草地类组型代号说明、西宁市区草地类型面积、载畜量统计数据（1988）、西宁市区草地类型面积、载畜量统计数据（2012）。数据表结构相似。例如西宁市区草地类型面积、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 compiles statistical data on grassland type area and livestock carrying capacity in the urban area of Xining, Qinghai Province, for the years 1988 and 2012. The data is classified and counted based on grassland group type codes. For instance, Roman numeral I represents alpine dry grassland type, II represents mountain dry grassland type, III represents alpine desert type, B represents medium graminoid group, and J represents shrub group, among others. 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 this dataset.

The dataset is compiled from the *Statistical Compilation of Grassland Resources of Qinghai Province* published by the Qinghai Provincial Grassland Station in 1988 and 2012.

This dataset includes three data tables, specifically: 1. "Instructions for Grassland Group Type Codes of Qinghai Province"; 2. "Statistical Data of Grassland Type Area and Livestock Carrying Capacity in Urban Area of Xining (1988)"; 3. "Statistical Data of Grassland Type Area and Livestock Carrying Capacity in Urban Area of Xining (2012)". The structures of these three tables are highly similar.

Take the table "Statistical Data of Grassland Type Area and Livestock Carrying Capacity in Urban Area of Xining (2012)" as an example, which contains a total of 8 fields:
1. Field 1: Type Code
2. Field 2: Grassland Type Name
3. Field 3: Grassland Area
4. Field 4: Available Grassland Area
5. Field 5: Average Fresh Grass Yield per Unit Area
6. Field 6: Average Edible Fresh Grass Yield per Unit Area
7. Field 7: Livestock Carrying Capacity
8. Field 8: Grassland Type Grade
