主要研究方向：生物多樣建模

目前具體開展以下幾個方面的創新研究：

1. 多樣性響應機制與理論框架

研究多樣性如何響應環境變化，綜合考慮物種生態變量、遺傳多樣性和擴散能力等關鍵因素。提出生命策略指數（LSI）這一綜合評估標準，用于預測氣候變化下不同動物類群的滅絕風險，為瀕危物種的科學管理和全球生物多樣性的保護提供科學依據。

2. 生物多樣性指標體系構建.

通過系統歸納歷史文獻和最新研究進展，構建生物多樣性的指標體系。深入總結分布聚集檢測和評估的統計指標，涵蓋不同實地調查方法、研究模型和抽樣尺度，提出開發新的分布聚集指標時可遵循的原則，為未來開發新的統計方法和指標提供指導。

3. 大尺度生物多樣性評估

關注生物多樣性在時間和空間上的延遲響應現象（如氣候債務）。以兩棲動物為研究對象，評估全球不同地區的氣候債務積累情況，分析景觀異質性對空間氣候債務模式的影響，為不同氣候變化情景下全球兩棲動物保護提供參考。

4. 野外調查尺度上的多樣性格局

研究物種的空間分布模式，提出新的加性框架來劃分局部多物種分布的聚集水平，用于野外生物多樣性數據的分析。該框架將物種的空間分布劃分為區域豐度變異和局部空間慣性效應，具有潛在的應用價值。

研究目標：

深入理解生物多樣性響應環境變化的機制。

開發和完善生物多樣性評估和監測的方法和指標。

提供科學依據和工具，為全球生物多樣性保護和管理決策提供支持。
