1971—2011年海南气候变化特点及其对农业的影响——以海南省儋州市为例

Climate Change and Impacts on Agricultural Production in Hainan from 1971 to 2011——A Case of Danzhou

通过1971—2011年气象资料统计分析,探讨儋州近40年气候变化。结果表明:在研究周期内气温呈现波动略微升高的趋势;降水量年际变化较大,总体呈现略微减少趋势,特别是近10年,降水量减少尤为明显。在此基础上,以儋州为例分析气候变化对海南热带农业的影响,提出在全球气候变化背景下,保障热带高效农业安全生产的对策与建议。

Studied the climate change in Hainan through the meteorological data of Danzhou from 1971 to 2011. The results showed that： during the study period temperature fluctuated and increased slightly. The inter-annual variation of precipitation was larger, and the precipitation slightly decreased, especially in recent 10 years, the decrease of precipitation was obvious. After that, taking Danzhou as an example, analyzed the influence of climate change on tropical agriculture, and put forward countermeasures and suggestions how to develop tropical and efficient agriculture under the background of global climate change.
