Group 1 - China is one of the countries with the richest plant diversity globally, with 65% of higher plant communities and 80% of nationally protected wild plants effectively protected since the "14th Five-Year Plan" began [1] - During the "14th Five-Year Plan" period, five national parks have protected 141 species of nationally protected wild plants and established over 300 conservation points for rare and endangered wild plant habitats [3] - The national plant conservation system, centered around the National Botanical Garden and the South China National Botanical Garden, has been scientifically established to ensure large-scale preservation of genetic resources and support research [3] Group 2 - The National Seed Resource Bank in Beijing has reached its structural completion, designed to hold 70,000 species and approximately 2 million samples, making it the largest plant genetic resource bank in China [7] - The facility is equipped with advanced preservation technologies, including long-term storage at -20°C and ultra-low temperature storage at -196°C, allowing for comprehensive preservation from seeds to DNA [7] - By 2035, the goal is to collect 30,000 species and achieve full coverage of China's endangered plants, aligning with world-class botanical gardens [9] Group 3 - The National Botanical Garden is actively registering seeds collected from various regions, ensuring proper documentation and quality control for conservation efforts [11][13] - The South China National Botanical Garden has completed key projects, including a data center, and currently conserves 12,077 plant species, including 987 endangered species [15]

央视网消息：我国是全球植物多样性最丰富的国家之一。"十四五"以来，通过统筹推进就地保护与迁地保护，全国65%的高等植物群落、80% 的国家重点保护野生植物得到有效保护，德保苏铁、杏黄兜兰等300多种濒危植物实现了野外回归。 "十四五"期间，首批已设立的5个国家公园就地保护了141种国家重点保护野生植物，在自然保护地外划建300余处珍稀濒危野生植物原生境保 护点，有效改善了栖息地的完整性、连通性，100余种极小种群野生植物得到抢救性保护。同时，以国家植物园和华南国家植物园为核心的迁 地保护体系的科学建立，为大规模种质资源保存和科研攻关提供保障。 在国家植物园，记者看到了原产自西非纳米布沙漠的世界级珍稀植物千岁兰。经过系统培育，一亿年前就存在的沙漠"活化石"如今在北京"子 孙满堂"。今年，我国完成首个千岁兰全生长周期图谱收集。 在国家植物种质资源预备库，工作人员正在给各地邮寄来的种子进行登记入库。 我国加速完善植物种质资源保护体系 种子库是防止物种灭绝的核心"保险柜"。在种子库中，珍稀植物的种子是怎么被保存的？一起跟随记者的镜头去看一看。 近日，位于北京的国家植物种质资源库主体结构封顶。这座设计容量达7万种约20 ...
