Paddy rice is one of the main grain crops in China. Accurate evaluation of rice planted area and spatial distribution are significant for the estimation ofgrain output and cropland allocation. Meanwhile, paddy rice is a main contributor to greenhouse gas emissions and therefore its cultivation and spatial distribution have significant implications for rising temperatures and global climate change...
Agriculture plays important role in economic and social development in China. Diverse climatic and geomorphological conditions make it difficult to monitor agriculture timely and accurately in China. In this paper, we demonstrated the application of GF-1 imager and data products in agricultural monitoring in China.
Image classifications including sub pixel analysis are often used to estimate directly the crop acreage, while ground data collected during field surveys play a secondary role. This type of crop area assessment using image classifications often leads to a biased estimation due to non-representative selection of training data and subjective a-priori knowledge. Instead regression estimator approach...

China's rape acreage and total output of rapeseeds ranks among the top in the world, accounting for more than 30% of the world's total rape acreage and output of rapeseeds. This paper takes Landsat TM as the main data source in conducting the study of extracting rape acreage information in the Shou County, Anhui Province. Through analysis and calculations of phenological diversity, spectral discrimination,...
BackgroundAlcohol consumption has been found to be associated with work‐related injuries among workers around the world, but this association has not well been studied among agricultural workers in China.
MethodsThis population‐based survey aimed to study the association between alcohol use and work‐related agricultural injury. Farmers in a northeastern province of China were questioned about work‐related...
