A Study on the Characteristics and Influencing Factors of Non-grain Conversion of Cultivated Land in Mountainous Areas of Hunan Province——A Case Study of Suining County
Based on the differences in labor input,"non grainification"is divided into light labor type and heavy labor type.Taking Suining County in the mountainous area as an exam-ple,the characteristics and influencing factors of"non grainification"are clarified,and control measures are proposed.The results show that:(1)the non grain oriented light labor force is evident in all townships,while the non grain oriented heavy labor force is only evident in Chengguan Township and Dongshan Dong Ethnic Township.(2)The degree of fragmentation of cul-tivated land patches is high,presenting as light labor type＞heavy labor type＞grain cultivated land.(3)The level of non grainification in light labor types shows an increasing trend with altitude and slope,while in heavy labor types,except for those below 250 meters above sea level,the overall trend of non grainification decreases with altitude,and there is no pattern of change with slope.(4)At the level of farmers,non-agricultural employment,wildlife destruction,transportation conditions,distance from the market town,and agricultural income significantly affect the"non grainification"of light labor forces;Agricultural income,dis-tance from the market town,and the area of cultivated land transfer significantly affect the heavy labor force oriented"non grainification".The research results aim to provide decision-making references for the control of non-grain production.
