摘    要:以在植被分布中起重要作用的温度指标(生长度·日,GDD)和水分指标(可能蒸散率,PER)为基础提出温度·水分影响函数f(GDD,PER),评价丁东北阔叶红松林分布区生态气候环境质量即生态气候适宜性.将f(PER,GDD)≥0.70划为阔叶红松林核心分布区;0.35≤f(PER,GDD)<0.70划为适宜分布区;f(PER,GDD)<0.35划为边缘分布区.东北阔叶红松林分布区面积为39.99km^2,其中核心分布区面积7.13×10^4kg^2,适宜分布区12.27km^2,边缘分布区20.59km^2。同时结合大气环流模式(GISS、OSU)的气候变化情景评价了全球气候变化对东北阔叶红松林分布区生态气候适宜性的影响.结果表明,于暖化气候条件下东北地区阔叶红松林分布区明显减小,生态适应性显著下降。

关 键 词:阔叶红松林  生态气候适宜性  温度-水分影响函数  气候变化  评价

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 39.99km 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.
Keywords:Broadleaved Korean pine forests  Eco  climatic suitability  Temperature  water effect function  Climate change  Assessment
