Assessment of eco-climatic suitability and climate change impacts of/on broad-leaved Korean pine forest in Northeast China
东北阔叶红松林分布区生态气候适宜性及全球气候变化影响评价

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 39.99km 2, which included the optimum distribution area 7.13 km 2, suitable area 12.27km 2,and marginal area 20.59 km 2. Under GISS and OSU climate 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.
