Satellite photogrammetry is an important way to obtain geospatial information of the earth, and it is also an effective way to solve the mapping issue for difficult areas in the world. The development process of optical surveying and mapping satellites are briefly summarized, and the optical surveying and mapping satellites of China are introduced in detail. After years of technological development, the results of optical photogrammetry satellites in China can meet the accuracy requirements of 1∶50 000 and 1∶10 000 scale surveying and mapping products. And the development status of optical surveying and mapping satellites are summarized, and the future development trends of surveying and mapping satellites are proposed, including on-board intelligent detection and storage, on-board and ground data intelligent processing, and multi-satellite network collaborative detection. With the support of global high-precision basic information data, the future photogrammetry satellites will be developed in the direction of an integrated, ubiquitous and intelligent type to improve the guarantee capability of surveying and mapping products.

目的：观察乌鲁木齐地区维吾尔族（维族）及汉族支气管哮喘患儿血清、维生素 D 水平变化，探讨其临床意义。方法选取支气管哮喘患儿175例作为观察组（汉族97例、维族78例）、健康儿童141例作为对照组（汉族90例、维族51例），采用 ELISA 法检测血清 IgE、1，25（OH）2 D3水平，采用直线相关分析二者的关系。结果观察组 IgE 水平高于对照组、1，25（OH）2 D3水平低于对照组（P 均＜0．05）；观察组维族患儿 IgE 水平高于汉族、1，25（OH）2 D3水平低于汉族（P 均＜0．05）。直线相关分析结果显示，维汉支气管哮喘儿童血清 IgE 水平与1，25（OH）2 D3均呈负相关（r维族＝－0．298、r汉族＝0．268，P 均＜0．05）。结论乌鲁木齐地区维汉支气管哮喘儿童血清维生素 D 水平均降低，尤以维族为重；维生素 D 可能参与了哮喘的发生发展。 [ABSTRACT FROM AUTHOR]
