Assessment of eco climatic suitability and climate change impacts of/on broad leaved Korean pine forest in Northeast China

Abstract

Abstract: Based on growing degree days (GDD) and potential evapotranspiration ratio (PER), the temperature water effect function (f(GDD, PER)) was established and the assessment of eco climatic suitability and climate change impacts of/on broadleaved Korean pine forests in Northeast China was studied. The results showed that the present distribution area of broad leaved Korean pine forests in Northeast China was 39.99km², which included the optimum distribution area 7.13 km², suitable area 12.27km²,and marginal area 20.59 km². Under GISSand OSUclimate change scenarios, the climate of Northeast China changed to warming and dry in some degree. Under this tendency, the distribution area of broad leaved Korean pine forests would be reduced,and the eco climatic suitability would be declined.

Key words: Broadleaved Korean pine forests, Eco climatic suitability, Temperature water effect function, Climate change, Assessment
