Spatial Pattern and Influencing Factors of Non-grain Cultivated Land in the Three River Basin (Yunnan Section)
In order to clarify the situation of non-grain farmland in typical hilly areas of southwest China and provide targeted control strategies,this study investigated the spatial distribution of non-grain crops taking the Three River Basin (Yunnan section) as the study region. The driving force of non-grain industrialization in this region was identified from the perspectives of cultivated land resource endowment,social and economic factors and agricultural input factors,and the driving types of non-grain industrialization were divided. The results showed as follows. 1) In 2019,the total non-grain area of the Three River Basin was 100.41 million hm2,and the average non-grain rate was 34.69％. The non-grain production degree of county-level units in the Jinsha River Basin was significantly higher than that in the Nujiang River Basin and Lancang River Basin. 2) Several significant characteristics that contributed to non-grain industrialisation included grain output per unit,share of rural population,slope,and per capita cultivated land area. 3) The driving types of non-grain-driven cultivated land mostly consisted of resource-driven,labor-driven,and economy-driven categories. The labor-driven type was identified as the predominant driving force in the region. Economy-driven type are all in county-level cities or municipal districts,while the resource-driven type is mainly concentrated in proximity to the economic-driven type. The pursuit of diverse approaches to managing non-grain farmland,based on variations in driving factors across different regions,can contribute to the development of evidence-based strategies for adjusting national policies related to food security and farmland preservation.
