China to strengthen ecological protection for more resilient ecosystems by 2030_我的网站
一 | 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.
。1月8日，据IT界网友反馈，四川电信开始邀请用户体验Volte，用户可以在打电话和打视频电话的同时上网。可打开免费回复信息“KTV”至10001。
二 | 但有网友反馈，四川电信已经支持Volte业务在营业厅开通。自去年11月29日起，中国电信Volte高清语音通话已全面开通商业试用。
三 | 电信用户需要使用支持Volte的设备终端来启动服务。
四 | 此外，他们需要重启手机或切换飞行模式，并在手机设置中启用Volte高清通话。手机信号栏显示HD或Volte，表示成功。用户可以尝试下载视频以测试呼叫是否成功。Volte，也称为Voice over LTE，也称为HD Voice。这就是手机中的“高清”图标的来源。它是一种基于4G网络的高质量语音和视频呼叫服务。Volte技术给4G用户带来最直接的感受是等待时间更短、质量更高、语音和视频通话效果更自然。Volte与2G和3G语音通话本质上不同。
五 | Volte是一种基于4G网络全IP的端到端语音方案。Volte使用高分辨率编码和解码技术，与2G和3G语音通话相比，它可以提高约40%的语音质量。Volte为用户带来较低的访问延迟（拨号后等待时间），比3G低50%，约2秒，而2G为6-7秒。此外，在2g和3g下，经常会出现辍学现象，但Volte的辍学率接近于零。
