Human-induced environmental changes threaten the functional stability of natural forest ecosystems. Understanding dominant factors influencing both space and in extremely heterogeneous environments is crucial for elucidating Here, 30 dynamic plots were established along successional pathway Maolan National Nature Reserve Southwest China. By measuring 15,725 stems across 286 distinct species’ six key plant traits, we constructed traits quantified redundancy (FR) vulnerability (FV) to represent stability, further utilized line model multiple linear regression explore biotic/abiotic indicators degraded karst forests. Additionally, as unfolded, contribution overall increased, from 59.85% 66.64%. These included specific leaf area (SLA), dry matter content (LDMC), thickness (LT) nitrogen (LNC), which played a role driving space. With increasing species richness (FR), entities (p < 0.001) FR while FV 0.01) decreased. The results also demonstrated higher forests (FR > 2). However, over 51% FEs consisted single species, with majority clustered into few (FEs), indicating an elevated level Soil nutrient availability significantly influences ecosystem’s explaining 87% variability 100% variability. Finally, rich SR could provide sufficient insurance effects; soil pH available potassium (AK) enhance resilience, exchangeable calcium (Eca), total phosphorus (TP) (TK) indicate resistance This study highlights complex mechanisms extreme habitat conditions, thereby deepening our understanding ecosystem function maintenance.
