China County Data Collection, Land Use
Listed in NASA Earthdata CMR
The Land Use dataset contains three variables which help describe the agricultural land use for China counties.
Description
The three variables are: 1) Cropland area (hectares), 2) Pastureland and Grassland area (hectares), 3) Area Sown (hectares). For Area Sown variable, areas which are double cropped are counted twice.
See the references for the sources of these data. China County Data collection contains seven datasets which were compiled in the early 1990s for use as inputs to the DNDC (Denitrification-Decomposition) model at UNH. DNDC is a computer simulation model for predicting carbon (C) and nitrogen (N) biogeochemistry in agricultural ecosystems.
