云南气候带变化对高原特色农业的影响及适应对策

Abstract:In the context of global warming，the climatic zones in Yunnan Province generally show an expanding/shrinking trend in the extent of the tropical and sub-tropical/temperate zones during the past 50 years. Moreover，the expansion toward high altitudes is more obvious than the northward shift for the warmer zones. Accompanied with changes in climatic zones and impacts of climate change，the instability of agricultural yields has increased，and the agricultural meteorological disasters and crop diseases and pests have become more frequent and severe，consequently resulting in an increased climate risk encountered by the Plateau Characteristic Agriculture in Yunnan Province. To adapt to climate change，some innovation practices have been conducted on the institution system and capacity building for the development of Yunnan Characteristic Agriculture. In order for better adaption，three suggestions are further proposed：（1）To carry out refined zoning on agroclimatic resources and climate risks，scientifically assess climate carrying capacity，and optimize and adjust industrial distribution and plant structure of Yunnan Characteristic Agriculture to make full use of the productive potential of agroclimatic resources.（2）To vigorously promote capacity building in the adaptation of Yunnan Characteristic Agriculture to climate change and strengthen the agricultural meteorological disaster risk management.（3）To speed up science and technology innovation and promotion in agricultural adaptation to climate change.
