Weight value of disturbance and Simpson Index of indigenous plant species diversity along agro-disturbance of Bai-gui Lake watershed in Ping-ding-shan City. We concluded that there is a significantly negative correlation between Simpson Index of indigenous plant species and weight value of disturbance (P<0.01). Disturbance is the dominant environment driver of indigenous plant species diversity decreased on risk assessment and early warning mechanism of agricultural non-point source pollution. Thus, understanding dynamic links between indigenous plant species diversity and weight value of disturbance can be not just applied to preserve of plant species diversity, but also applied to risk assessment and early warning mechanism of agricultural non-point source pollution along different disturbance gradient.
