Combining Spatial and Survey Data to Explain Participation in Agricultural Land reservation Programs
通过马里兰州四个县的农业土地所有者调查和GIS空间数据，分析了影响参与农业土地保留项目的因素，发现农场规模、作物种植、子女继承意愿等增加参与可能性，而靠近城市则降低。
<i>The factors influencing participation in both purchase of development rights and transfer of development rights farmland preservation programs are analyzed using data from a survey of agricultural landowners and from spatial data on individual farms collected using GIS for four Maryland counties. Generally, the likelihood of participation increases with farm size, growing crops, if a child plans to continue farming, eligibility and the share of income from farming. Landowners closer to the nearest city were less likely to join. Survey information about landowner characteristics and local selection committees may aid in targeting efforts.</i>
