Green-depressing cropping system: A referential land use practice for fallow to ensure a harmonious human-land relationship in the farming-pastoral ecotone of northern China

摘要: Abstract The farming-pastoral ecotone of northern China (FPENC) is a fragile ecosystem that severely suffers from the acute contradiction between population growth and limited land resources. Chinese government emphasized rehabilitated agriculture, such as current government-led fallow, should be developed in FPENC. However, what kind farmland needs to lay how manage fields during fallow periods, duration periods are unclear. Fortunately, green-depressing cropping system (GDCS) (Yaqing Pinyin) has existed for approximately 300 years also use practice reduce intensity recover soil property something common with field selection management, can serve reference specific policy. Therefore, we aimed improve our understanding GDCS provide recommendations future policies. Given this, an approach using satellite data map was explored, this information combined questionnaire survey help understand state Then, factors influencing farmers’ willingness adopt FPENC were evaluated binary logistic regression model (BLR). results indicated still widely distributed FPENC, 3.34 % 2.31 total arable Shangdu experienced 2019 2018, respectively. Furthermore, farmers Houshan area had higher than Qianshan area. More specifically, passive predominated suboptimal choice due severe drought, while older agro-pastoral households active GDCS. Ultimately, plays important role improving fertility conserving water, leading increase at least 50 crop yields year immediately following implementation. Finally, according factor analysis, concluded program first performed regions high proportions dryland sloping fields, small resident population, levels mechanization transfer rates. Additionally, by omitting enough recover, different subsidies required encourage implement practice.
