气候变化对我国北方农牧交错带及其气候生产力的影响
The Impacts of Climate Change on the Interlock Area of Farming-Pastoral Region and its Climatic Potential Productivity in Northern China
摘要
Abstract
In this paper, based on the climate data(1961-1995) of 63 stations in northern China, and according to the climate analysis about 40 years, the impacts of climate change on the boundary and climatic potential productivity of the interlock area of farming-pastoral region were conducted by using proper boundary indexes and calculating methods. The result showed that in the future climate change scenarios (temperature increasing and precipitation unchanging), the interlock area of farming-pastoral region will shift from the northwest to southeast, and the climate potential productivity will decrease. But if the temperature and precipitation increase at same time, the transfer of interlock area of farming-pastoral region will decrease, or keep unchanging. And the climatic potential productivity will increase. The precipitation is the key factor to determine the boundary and climatic potential productivity of interlock area of farming-pastoral region in northern China.
