“…Previous studies have attempted to clarify the major influencing factors of the distribution pattern of IAPs in China [ 31 ]. Some studies have reported that biogeography and socio-economic factors are both important [ 33 , 50 ], while some studies have concluded that environmental factors play a more important role [ 15 , 32 , 51 ]. Generally, for native plants, low temperature is the primary limiting factor affecting distribution [ 40 ].…”

“…Previous studies showed that the combination of environmental and anthropogenic factor variables can effectively predict the distribution pattern of invasive alien plants [ 15 , 31 , 32 , 33 , 37 , 50 ]. For example, Li and Shen selected seven climatic variables and three socio-economic variables to analyze their role in shaping the distribution patterns of IAPs [ 15 ].…”

“…For example, Li and Shen selected seven climatic variables and three socio-economic variables to analyze their role in shaping the distribution patterns of IAPs [ 15 ]. Zhou et al evaluated the impact of six climatic factors and three socio-economic variables on the differential strategies of IAPs [ 50 ]. We integrated previous studies to select variables that are assumed to affect the distribution pattern of IAPs.…”

In recent years, invasive alien plants (IAPs) have caused serious ecological disasters and economic losses in China. This study combined three IAP species richness-related indices (species richness of IAPs, first records of IAPs, and the relative species richness of IAPs), as well as indices reflecting distribution and dispersal patterns (average similarity coefficient of IAPs) and invasiveness (average risk score of IAPs), to conduct an integrated regional-invasion risk assessment based on the principal component analysis (PCA) method. Partial least-squares (PLS) regression was conducted to explore the explanatory power of 12 environmental and anthropogenic factors on different invasion indices. The results indicated that coastal provinces and Yunnan had high IAP introduction risk, as well as high synthetic-risk scores. The dispersal of IAPs in mid-latitude provinces should be particularly prevented. For species richness of IAPs, more environmental factors with variable importance for the project (VIP) values higher than 1 were retained in the optimal model, reflecting the importance of environmental filtering on IAPs. Visitors were the most important predictor for first records of IAPs. Compared to species richness (R2 = 79.5%), first records were difficult to predict (R2 = 60.4%) and were influenced by anthropogenic factors. There was spatial distribution congruence of various families of IAPs. Generally, the correlations of the residuals of species richness were still significant, with 0.421 (p < 0.05) as the lowest Pearson correlation coefficient, which indicated that external factors could not fully explain the spatial distribution congruence. These findings could enrich the relevant research on IAP invasion mechanisms and provide suggestions for regional IAP detection and response.

“…Presumably the climate of the Daba Mountains is similar to that where plants are found in their natural environment in America, allowing IAS to colonize and spread more readily. One reason for the high levels of invaders from the American continent is that many have been reported to exert clear allelopathic effects on native species [98][99][100][101]. Intentional introduction also constitutes a high percentage (65.63%) in all pathways of introduction.…”

The southern side of the Daba Mountain area is a hotspot of global biodiversity and an essential barrier promoting ecological security. However, knowledge about the distribution status and transmission pathways of invasive alien species (IAS) in this area is limited. We counted the IAS on the southern side of the Daba Mountain area through sample transects and analyzed the factors affecting their spatial distribution. We also assessed IAS risk using the analytic hierarchy process (AHP), which found 64 IAS belonging to 23 families and 53 genera. Around rivers and roads, the results showed a vertical two-way dispersal pattern. Human and environmental factors, such as a very dense transportation network, can affect the distribution pattern of IAS. AHP assessed 43 IAS (67.19%), primarily distributed in villages and towns, as being of high or medium risk. High- and medium-risk IAS should be the focus of invasion prevention and control, and priority should be given to controlling the spread of IAS around rivers and roads.

“…Our results show that anthropochory is the most important dispersal strategy for alien and rare plants to adapt to disturbed environments (Figure 1). However, anthropochory in alien plants is mainly unintentional (e.g., hidden in goods, cars, hay, or accidentally mixed with grain) [47] and in rare plants it is intentional (e.g., sold for agriculture and gardening) because more than 60% of the rare plants are Orchidaceous and medicinal plants, which are often cultivated and traded. Zoochory is used more by alien plants for diaspores with spiny or hooked appendages, facilitating spread in disturbed environments [16,47].…”

Alien and rare plants tend to adapt to contrasting biotic and abiotic conditions. However, adaptability assessments of alien and rare plants using biological and habitat characteristics in stressful and disturbed environments are limited. We collected and demonstrated the biological and habitat characteristics and assessed the adaptive capacity of alien and rare plants in China using the analytic hierarchy process. Biological characteristics, such as dispersal strategy, sexual and asexual reproduction modes, life form, and habitat characteristics (e.g., habitat type and distribution spatial extent), are important indicators of the adaptability of alien and rare plants to stressful and disturbed environments. Alien plants have a higher adaptive capacity to disturbed environments than rare plants, while rare plants have a higher adaptive capacity to stressful environments than alien plants. Stressful and disturbed environments constrain the adaptive capacity of alien and rare plants, respectively. However, the constraint on alien plants from stressful environments is weaker than that on rare plants from disturbed environments. Understanding the adaptive capacity of alien and rare plants will help researchers and policymakers develop strategies for preventing the invasion of alien plants as well as protecting rare and endangered plants.
