Abstract
濒危植物秦岭冷杉地理分布和生物 生态学特性研究张文辉 1 3 许晓波 2 周建云 2 孙玉玲 3 谢宗强 3 1 (天津师范大学 , 天津 300074) 2 (西北农林科技大学 , 陕西杨凌 712100) 3 (中国科学院植物研究所植被数量生态学重点实验室 , 北京 100093) 摘要 : 秦岭冷杉 ( A bies chensiensis) 为中国特有三级保护植物 ,仅岛屿化分布于陕西 、 甘肃 、 四川 、 河南的秦巴山地和 湖北神农架中高山地区 ,分布海拔 1300 -2300 m。为了对秦岭冷杉种群进行深入研究和有效保护 ,通过样地调查 和相关资料分析 ,对其地理分布 、 群落特性 、 种群特性进行了系统研究 。秦岭冷杉群落包含种子植物 40 科 63 属 102 种 ,可划分成 11 个地理区系成分 ,其中温带分布型属占 84.21 % ,热带分布型属占 15. 79 % ,温带分布是群落的 基本特性 。秦岭山区的秦岭冷杉群落可分为 5 个群丛 ,基本特点为 :生境阴湿 ;群落郁闭度大 ,结构复杂 ;种群个体 年龄差异大 ;天然更新主要发生在保护较好的阴坡林窗地段 。秦岭冷杉苗期生长缓慢 ,在 30 -70 年龄阶段 ,高生 长旺盛 ;在 40 -100 年龄阶段 ,胸径生长较快 。秦岭冷杉开始结实年龄在 30 -40 年龄阶段 ,结实间隔期为 3 -5 年 。 秦岭山区成熟个体平均产球果 8 个/ 株 ,饱满种子 56 粒/ 球果 。种群更新的关键问题是种子产量低 ,林下幼苗稀

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
