摘　　要：运用“资源二号”卫星影像并基于“3S”技术开展陕西省经济林普查,获得全省107个县(区)经济林资源数据。通过遥感判读和实地验证,利用函问调查数据补充、年鉴数据控制和检验,分析了陕西省经济林资源规模及空间分布特征,并以此提出陕西省苹果、梨、猕猴桃、核桃、板栗、红枣、花椒等经济林品种的潜在适宜发展区。认为陕西省经济林发展具有地带性和集聚性特征明显、产业综合竞争力强,鲜果综合管理条件优于干杂果、关中经济林综合管理条件优于陕北和陕南,空间分布呈现重点产区向周边辐射的趋势,规模发展与提质增效空间巨大等优势;提出可进一步优化全省经济林产业空间布局,实施果业转型升级、实现由产业大省向产业强省转变,转变经营模式、建立专业化、规模化经济林产业园等发展建议。The economic forest census in Shaanxi Province was carried out to obtain the economic forest resources data of 107 counties (districts) by using the satellite image of “Resources 2” and the “3S” technology.The scale and spatial distribution characteristics of economic forest resources in Shaanxi were analyzed based on remote sensing interpretation,field verification,supplementing survey data and yearbook data,and the potential suitable development areas of economic forest varieties such as apple,pear,kiwifruit,walnut,chestnut,red jujube and pepper in Shaanxi were put forward.It was considered that the development of economic forests in Shaanxi was characterized by zonality and agglomeration,strong industrial competitiveness,better comprehensive management conditions for fresh fruits than dry and miscellaneous fruits,and better comprehensive management conditions in the central Shaanxi plain than northern and southern Shaanxi,which showed the trend of radiation from key producing areas to surrounding areas on the spatial distribution,and the space for scale development and quality improvement was huge.Some suggestions were put forward for further optimizing the spatial distribution of economic forest industry,implementing the transformation and upgrading of fruit industry,realizing the transformation from a big industrial province to a strong industrial province,transforming the management mode,and establishing specialized and large-scale economic forest industrial park.
