Crop pest and disease used in this project

The crop pest and diseases survey(CPD) data is a published dataset of aggregated CPD occurrence ratio at the province level of the period from 1980 to 2017. CPD records of National Agricultural Technology Extension and Service Center. This dataset is based on the survey data originating from a bottom-up crop protection network that takes responsibility of surveying the CPD condition and recording the occurrence of CPD. Notably, crop protection only recorded those species of CPD that lead to yield reduction or failure.

作物病虫害调查（Crop Pest and Diseases Survey，CPD）数据集是一套公开数据集，收录了1980年至2017年间省级尺度下的聚合CPD发生比例数据。该数据集的数据源自全国农业技术推广服务中心的CPD记录，基于一套自下而上的作物保护网络采集的调查数据构建，该网络负责开展作物病虫害状况调查并记录CPD的发生情况。值得注意的是，该网络仅记录那些会导致作物减产或绝收的CPD物种。
