Spatial Risk Assessment of Alien Plants in China Using Biodiversity Resistance Theory
Pp. 143-148 (6)
In the present chapter, the potential occurrence risk of invasive plants across
different provinces of China is studied using disease risk mapping techniques (empirical
Bayes smoothing and Poisson-Gamma model). The biodiversity resistance theory which
predicts that high-biodiversity areas will have reduced risk of species invasion serves as
the base for performing spatial risk assessment of plant invasion across provinces. The
results show that, both risk mapping methods identified that north-eastern part of China
have the highest relative risk of plant invasion. In contrast, south-western and southeastern
parts of China, which have high woody plant richness, are predicted to possess
low relative risks of plant invasion. For the future, it is interesting to compare the spatial
risk patterns across different functional groups of these alien plants. The results of this
chapter has been published in an open-access journal .
