| 紫茎泽兰是云南省主要入侵毒害草之一,为摸清紫茎泽兰在全省草原中的优势分布现状,以
云南省草原基况监测成果为基础数据,对紫茎泽兰优势发生面积、分布现状、生物量、载畜量、NPP、

| 英文摘要: |
| Eupatorium adenophorum is one of the major invasive toxic weeds in Yunnan Province. To
clarify its dominant distribution status in grasslands across the province, this study utilized the grassland
monitoring data of Yunnan as the baseline to evaluate and analyze factors such as the dominant occurrence
area, distribution status, biomass, livestock carrying capacity, net primary productivity(NPP), precipitation
use efficiency(PUE), and ecosystem service value of Eupatorium adenophorum. The results
showed that the dominant occurrence area of Eupatorium adenophorum in grasslands of Yunnan Province
was 79 494.12 hm2, accounting for 6.07% of the total. It was found in all nine grassland types,with the largest distribution area in tropical shrub-grasslands (38 586.14 hm2, 48.54%) and the smallest in
artificial grasslands (123.24 hm2, 0.16%). Alpine meadows had the highest vegetation coverage (90.00%).
Sloped terrains had the largest dominant occurrence area (47169.43 hm2, 59.34%). The spatial distribution
of grassland NPP generally decreased from south to northwest, with an average of 1 118.13 g·C/m2·a—
highest in Xishuangbanna Prefecture and lowest in Zhaotong City. PUE exhibited strong spatial heterogeneity,
averaging 1.12 g·C/m2·mm·a, with the highest value in Dali Prefecture and the lowest in Lijiang
City. The total ecosystem service value was 7.157 billion yuan/a, with Wenshan Prefecture having the
highest and Zhaotong City the lowest. Eupatorium adenophorum is abundant and widely distributed, making
rational classification-based control and enhanced utilization research important future directions. |
