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 39.99 km2, which included the optimum distribution area 7.13 km2, suitable area 12.27 km2, and marginal area 20.59 km2. 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.

摘要

基于生长度日（GDD）和潜在蒸散比（PER），建立了温度-水分效应函数（f（GDD，PER）），并对中国东北阔叶红松林的生态气候适宜性及气候变化影响进行了评估。结果表明，中国东北阔叶红松林目前的分布面积为39.99平方千米，其中最适宜分布面积为7.13平方千米，适宜分布面积为12.27平方千米，边缘分布面积为20.59平方千米。在GISS和OSU气候变化情景下，中国东北气候在一定程度上呈现变暖和变干的趋势。在此趋势下，阔叶红松林的分布面积将减少，生态气候适宜性也将下降。
