首次利用TM遥感资料提取了上海市菜地的分布信息,并以此为根据,制作了1995年上海市1∶10万菜地分布的遥感影像图和线划图,取得了令人满意的效果。有关研究成果已提交市政府有关决策部门,为上海市新一轮“菜篮子”工程的建设提供了及时、准确的信息。同时,为利用TM遥感资料提取像菜地那样总量少、田块小、分布零碎、光谱离散度大的农作物积累了经验,在遥感技术为农业服务方面开辟了一个新的应用领域
Using TM remote sensing data for the first time to extract the distribution information of Shanghai vegetable plots, and based on this, the remote sensing image and line drawing of the distribution of 1:10 000 vegetable plots in Shanghai in 1995 were produced and satisfactory results were obtained . Relevant research results have been submitted to the municipal government decision-making departments for the construction of a new round of “vegetable basket” project in Shanghai to provide timely and accurate information. At the same time, it has accumulated experience in using TM remote sensing data to extract crops with less total amount, small field size, fragmented distribution and large spectral dispersion like vegetable field, opening up a new application field for agricultural service by remote sensing technology
