摘要
对于农户土地利用行为差异及其变化特征的研究是农户土地利用行为研究的基础,本研究从农户土地利用决策角度出发,把农户土地利用行为的内涵界定为土地利用方式、土地利用程度和土地投入强度三个方面,采用方差分析、统计分析的方法,以辽宁省沈阳市苏家屯区238户农户的调查问卷为基础,研究结果表明:大城市郊区农户土地利用行为存在明显的差异,具有明显的"非农化"与"非粮化"的趋势,其中近郊区农户以"粮食需求"为主,土地利用程度低,土地投入强度小;远郊区农户以"粮食需求和利润需求协调"为主,农户土地利用程度较高,土地投入强度较大;纯农村农户以"利润需求"为主,土地利用程度最高,土地投入强度最大。最后,提出政府应该从适度扩大生产规模、加大农业科技投入和推广力度、优化农业生产布局等方面引导农户合理利用土地资源,实现土地利用效率的提高和土地资源的可持续利用。
The study on the differences and change characteristics of farmers＇ land use behaviors is the basis of the research on the behaviors. From the perspective of farmers＇ land-use decisions, this study defined the connotation of farmers＇ land use behaviors as land use pattern, land use degree and intensity of land input. Besides, with the methods of variance analysis and statistic analysis as well as the basis of questionnaires of 238 farmer households in Sujiatun District of Shenyang City, Liaoning Province, we got the following results： 1） The differences are significant with an obvious trend of ＂non-agricultural＂ and ＂non food.＂ In peri-urban areas, farmers have a greater preference for ＂grain demand＂, causing the low land use degree and weak land input intensity; in outer suburbs, farmers prefer the ＂coordination between grain demand and profit demand＂, which leads to higher land use degree and stronger land input intensity; the pure rural residents give priority to ＂profit demand＂, which results in the maximum land use degree and land input intensity; 2） In the suburbs of big cities, labor input in farming and industrial sectors have great differences. The transfer of labor from agriculture to non-agricultural industries, and agriculture from field crops to cash crops were evident; 3） The capital investment is very different. The farmers＇ input in cash crops is much higher than that in field crops; 4） The driving factor of differences in factor input is the expectation of the future profits of land use. Therefore, the government should guide farmers to use the land resources reasonably so that the improvement of land use efficiency and sustainable use of land resources could be achieved from several aspects such as moderately expanding production scale, increasing investment in agricultural technology and promotion efforts and optimizing the agricultural production layout.
