Agroecological geology groups and types are a comprehensive result from agroecological geology investigations, and are the basic units for the investigation and mapping. 農(nóng)業(yè)生態(tài)地質(zhì)類型是農(nóng)業(yè)生態(tài)地質(zhì)調(diào)查研究綜合性成果之一

The phenomena of agroecological environment are becoming worse and worse in the arid and semi-arid regions that has become the predominant obstacle for agriculture development. 在干旱、半干旱區(qū),農(nóng)業(yè)生態(tài)環(huán)境日益惡化的現(xiàn)象比較嚴(yán)重,已成為農(nóng)業(yè)發(fā)展的重大障礙。
