为了查清宜宾市油樟资源的空间分布、分析影响油樟发展的地形因素、提供油樟种植的基础资料，采用遥感影像判读与实地调查相结合的方法，对宜宾市境内面积大于350 m2且以油樟为优势树种的林地进行了调查和统计.结果表明：截止2012年底宜宾市共有油樟林26059.85 hm2，其中宜宾县的占66.4%，翠屏区的占33.6%，主要分布在46个乡镇，形成了以隆兴－古柏和宗场－思坡为中心的两个核心区；现有油樟以幼龄林为主，主要分布在坡度较小、光照较充足的山坡上，斑块面积普遍偏小，破碎化较严重，难以形成完整的油樟林生态系统.各个林龄段的比重和空间分布特征，显示油樟近几年由传统种植区快速向外扩张，说明油樟产业正受到越来越多的重视.

Cinnamomum Ionge-paiculatum planting is one of the major industries in Yibin. To identify the Cinnamomum Ionge-paiculatum spatial characteristics and the influence of topography, forest land patches more than 350 m2 and domi?nated by Cinnamomum Ionge-paiculatum were statistically analyzed on the basis of establishing systemic key of remote sensing interpretation and field survey. The results show that there are 26 059.85 hm2 dominated by Cinnamomum Ionge-paiculatum found in 46 townships in Yibin by the end of 2012, among which 66.4%are in Yibin County and 33.6%in Cuiping County. Most of the forest lands are distributed in hillside with enough sun irradiation and with a falling gradient within the range of 0 and 35 degrees. Severe fragmentation indicts that it is difficult to form full-scale ecosystem of Cinna?momum Ionge-paiculatum. The ratio of different stand age and spatial characteristics show significantly that Cinnamo?mum Ionge-paiculatum forest are spreading outside the traditional center of Longxing-Gubai and Zongchang-Sipo, which means more attentions are paid to Cinnamomum Ionge-paiculatum industry.
