摘 要：
利用温室、大棚等设施进行蔬菜种植,一直是我国北方蔬菜种植的主要方式之一,因此,及时、准确地获取大棚菜地的面积及分布状况,是确保政府"菜篮子"工程顺利实施的需要,也是关系民生的一项重要工作。为探索及时准确提取大棚菜地信息的技术方法。该研究以山东省寿光市为例,采用HJ-1卫星图像,在分析各主要地物光谱特征的基础上,结合研究区的背景资料以及专家知识,对遥感影像进行分类,准确提取了大棚菜地的信息。通过在影像上随机抽取样本点,结合RGB假彩色合成影像及部分实地调查资料进行精度分析,得出样本点总体精度为92.01%。该研究表明,在HJ-1影像中大棚菜地光谱特征明显,易于同其他地类区别,利用遥感影像提取大棚菜地信息的方法,适合北方地区大棚菜地信息提取。

摘 要：
Greenhouse Vegetables production played important role in guaranteeing vegetables supply for the citizens.In this paper,the authors tested the greenhouse vegetables land monitoring technique in Shouguang of Shandong using remotely-sensed HJ-1 imagery.Based on the analysis of the spectral characteristics of land cover types in HJ-1 image,the authors made remote sensing classification to retrieve the information of greenhouse vegetables.The overall classification accuracy is 92.01% through randomly sampled points conbined with the analysis of RGB false color composite images and field investigation.This study showed the greenhouse vegetables land had obvious spectral features in HJ-1 imagery and could be distinguished easily from other land cover types in the study region.This paper suggested that the method may be applicable in other region in northern China.
