9月13日21时18分，中国文昌航天发射场，由航天科技集团一院抓总研制的长征七号A运载火箭点火升空，成功将“中星1E”卫星送入预定轨道。 China will step up efforts to strengthen ecological conservation during the 2026-2030 period as it continues to pursue green modernization, according to a recently issued development plan.
The plan, jointly issued by the Ministry of Ecology and Environment, the Ministry of Natural Resources and other departments, said China aims to steadily improve the quality of its ecosystems, enhance ecosystem diversity, stability and resilience, and better safeguard the country's ecological security.
The plan also sets specific targets for the period, including keeping the proportion of land area covered by protected areas at no less than 18 percent of the country's total land area and raising the Ecological Quality Index (EQI) to 86.5. It also calls for increasing the soil and water conservation rate to above 74 percent and raising the forest coverage rate to 25.8 percent.
It also outlines tasks to further optimize the ecological spatial configuration, advance ecosystem protection and restoration, and comprehensively strengthen biodiversity conservation.
China has continued to strengthen ecological conservation and environmental protection. The country's landmark Ecological and Environmental Code, set to take effect this Saturday, marks another major step in these efforts, providing stronger legal support for sustainable and environmentally friendly development.

长七A火箭是我国新一代中型运载火箭的主力构型，具备一箭一星和一箭双主星发射能力，地球同步转移轨道运载能力不低于7吨，填补了我国运载火箭地球同步转移轨道5.5至7吨运载能力的空白。长七A火箭主任设计师魏远明介绍，本次任务长七A遥五火箭采用整流罩直径4.2米的构型，全箭高度60.1米，是长征家族最高的火箭之一。
B | 值得一提的是，长七A火箭作为我国首型采用助推器与芯一级集束式分离技术的捆绑火箭，相比以往火箭减少了一次分离环节，使火箭捆绑连杆结构更加简化。同时，集束式分离也减少了一个助推器落区，整个组合体都在一个落区内，更加有利于控制火箭残骸落区。此次任务的第二个亮点就是流程得到大幅缩减，工作效率大幅提升，型号队伍通过优化流程顺序、并行工作、合并测试等方法，将发射技术流程由32天缩减至26天。其中，总装模式由“一气呵成”改为“随到随吊”，总装时间减少3天；将具备类似状态的测试进行了一次合并“同类项”，测试时间减少2天；“串行变并行”，转场及发射区工作省下1天。6天听起来不长，但对于火箭发射来说，每一项工作都是争分夺秒，测发周期每减少一天，在火箭发射效率提高上就是向前迈进一大步。（总台央视记者 崔霞 李宁 陶嘉树 孙熙然 张雅臻 航天科技集团一院 高诗淇 桑茜 王冰 肖国军 姜文博）
