| 摘 要： | 本文研究了金沙江干热河谷攀枝花段不同土壤肥沃性条件下麻疯树的个体衰老状况及其生态复壮问题。将调查群落的生境质量划分为优秀、适宜与不适宜3类，统计分析生境间老树的地径、树高、冠幅、年龄、果实大小、种子大小等差异性，总体差异显著而两两之间差异受到遮阴类不适宜生境的影响而不普遍。麻疯树个体在优秀生境中衰老延迟，更新与生殖能力相对较好，而不适宜生境中衰老提前，更新与生殖能力相对较差。土壤瘠薄的三堆子截干树体更新能力相对较弱，而土壤肥沃的骨粉厂与沙滩则更新与生殖能力较强。麻疯树老树更新、生殖能力与L-H-S生态适应对策有很好的契合，能解释不同生境质量下高度、新梢和种子大小的正向匹配性。 |

| Abstract: | In this paper,studies vere made of the individual senescence status of Jatropha curcas and its ecological rejuvenescene under different habitat quality in the Jinsha River's dry-hot valley of Panzhihua section.The habitat quality of J.curcas was classified as three types:excellent,fit and unfit.Statistatical analysis was made of the significant difference of diameter,height,crown width and age,fruit and seed size of old trees in varied habitats but the difference among both was not common.In the excellent h... |
