The Evaluation Indexes and its Applications of Disused Arable Lands

It's a serious problem that there are many disused arable lands (DAL) in rural area at present. In the study of DAL, there are some problems such as indefinite concept, absence of evaluation indexes and quantitative research, which hinder to study it in a deep-going way. By analysis, DAL can be defined as a status that cultivated lands are left unused or made no full use owing to the peasants' subjective abandonment. Degree of DAL, area of DAL and loss of DAL are main evaluation indexes. The study will go deep and provide convenience to the rural work.
