摘 要: | 笔者以宁夏盐池县、同心县404户农户抽样调查数据,对农牧交错区农户耕地变化特征进行了分析,并采用Logistic模型计算,分析了农户耕地变化的影响因素。结果表明:农户家庭耕地面积差异较大,近30年,研究区农户人均耕地面积减少了0.23 hm~2。农田水利设施建设和政府政策引导引起农户农作物种植结构发生变化。外出务工人数占家庭人口比例、政策因素和非农收入对耕地面积变化的影响较为显著,是影响农户家庭耕地面积变化的主要因素。

Empirical Analysis of Farmland Change in Farming-pastoral Interlaced Region |
| |
Abstract: | Farmland change is essential to the agricultural modernization and national food security and has aroused a wide concern. This paper, based on spot check data of 404 farmers in Yanchi and Tongxing county where located in Ningxia Hui Autonomous Region, analyzes features of farmland use change in farming-pastoral interlaced region, applies logistic model to analysis the influencing factors of cultivated land use change. The results showed that the farmland area were much difference in peasant family. In recent 30 years, the farmland areas per person has decreased by 0.23 hm2 in study area. Meanwhile, crop planting structure has changed which caused by farmland water conservancy works and government policies. Households with the rate of farm labors was family populations, policy factors and the income of non-agriculture, were more likely to farmland area change, its the main factors for peasant family"s farmland area change. |
