| 摘 要： | 山东半岛是我国重要的果园基地,素有水果之乡的美誉。快速、准确地获取其面积及分布状况,是果园业健康发展和科学管理的客观需求。以山东省半岛北部沿海城市龙口市为例,以2005.6.13的TM影像为主要信息源,在深入分析各主要地物光谱特征的基础上,通过DEM数据建立地理控制区,把研究区分为海滨平原区和丘陵区。在海滨平原区,主要通过NDVI方法,建立果园提取模型;在地物构成相对复杂的丘陵区,建立基于光谱知识和地学知识相结合的果园提取模型,均取得了很好的效果。研究表明,龙口市2005年的果园地面积为316001.2Ha,集中分布于龙口东部的石良、兰高等乡镇。

| Abstract: | Praised as fruit hometown,Shandong Peninsula is an important orchard base in China.How to obtain the distribution and area of orchard rapidly with high precision is very helpful for healthy development and scientific management of orchard industry.Taking Longkou Prefecture,which is located at northern costal region of Shandong Peninsula,as an example,the technique of extracting orchard information is studied in this paper based on Landsat TM image acquired on June 13th,2005.Based on the analysis of every object's spectrum feature,and by construction of geographical control region based on DEM data,the whole study area is divided into two categories,costal plain region and hill region.In the costal plain region,the orchard information is extracted by means of NDVI.While in the hill region,it is extracted by means of integrated model with spectral knowledge and geoscience knowledge.Mainly distributed in Shiliang and Langao townships,the total orchard area is 316001.2Ha in Longkou prefecture in the year 2005.And the precision of orchard information extraction is 91.6% which is high enough for application. |
