基于知识规则的黑河流域土地覆被分类数据（2009）

基于知识规则的黑河流域土地覆被分类数据是利用基于知识规则的土地覆被分类方法制作而成，是一套与USGS全球土地覆被分类标准一致的、可以用于大气模式以及陆面过程模式的黑河流域土地覆被类型分布数据。
该数据覆盖黑河流域上、中、下游，采用Albers等面积割圆锥投影，空间分辨率1km，为一个含有土地覆被分类编码的ASCII码文件，命名为：Rule_Based_Lulc_of_HRB2009.asc，文件可直接用文本程序（如记事本）打开察看，也可导入ArcGIS进行其他操作。
另提供数据配套的NOAH陆面过程参数表和参数表说明，用户可参考该参数表将数据应用到陆面过程模型中，两文件分别为USGS_LULC_NOAHVEGPARM.TBL和NOAHVEGPARM_documentation.txt，均可用文本程序（如记事本）打开。

The knowledge rule-based land cover classification dataset of the Heihe River Basin (HRB) was developed using a knowledge rule-based land cover classification method. It is a set of land cover type distribution data for the HRB that conforms to the USGS global land cover classification standard and can be applied to atmospheric models and land surface process models.

This dataset covers the upper, middle and lower reaches of the Heihe River Basin, adopts the Albers equal-area conic projection, and has a spatial resolution of 1 km. It is an ASCII file containing land cover classification codes, named Rule_Based_Lulc_of_HRB2009.asc. The file can be directly opened and viewed with text programs (e.g., Notepad), and can also be imported into ArcGIS for other operations.

Additionally, supporting NOAH land surface process parameter table and its documentation are provided. Users can refer to this parameter table to apply the dataset to land surface process models. The two files are named USGS_LULC_NOAHVEGPARM.TBL and NOAHVEGPARM_documentation.txt respectively, both of which can be opened with text programs (e.g., Notepad).
