BACKGROUND: The growing season (GS) has been understood as a useful indicator for climate change due to high relationship with increasing temperature. Hear this study was conducted to examine changes in the thermal GS over South Korea from 1970 to 2013 based on daily mean air temperature for assessing the temporal and spatial variability in GS. METHODS AND RESULTS: Three GS parameters (starting date, ending date, and length) were determined at 19 stations throughout South Korea. The results show that the GS has been extended by 4.2 days/decade between 1970 and 2013 on average. The growing season start (GSS) has been advanced by 2.7 days/decade and the growing season end (GSE) has been delayed by 1.4 day/decade. Spatial variation in the GS parameters in Korea are shown. The GS parameters, especially GSS, of southeastern part of Korea have been changed more than that of northwestern part of Korea. The extension of GS may be more influenced on earlier onset in spring rather than later GSE. CONCLUSION: Under climate change scenarios, the GS will be more extended due to delayed GSE as well as advanced GSS. And These are more notable in the northeastern part of Korea.

산간 계곡의 지하배수관 설치에 따른 벼 냉수피해 사례분석

산간지역의 계곡 물길의 매립과 지하배수관의 설치에 따른 인근 논에서 벼 냉수해에 대한 민원이 제기되어 벼 냉수해와 지하배수관 설치의 연관성 유무을 파악하기 위해서 현장조사 및 분석을 실시하였다. 결론적으로 지하배수관 설치로 인하여 계곡물의 온도가 지하배수관 설치 전보다 0.5~4.5℃ 범위로 낮아진 것으로 분석되었고, 이 냉수를 농업용수로 관개한 하류쪽 논에서는 벼 냉수해가 발생할 가능성이 매우 높았을 것으로 판단되었다. 따라서, 적절한 수온상승 조치를 취하지 않으면 냉수해로 인하여 정상적인 수확이 불가능할 것으로 평가되었다. The complaint was filed for the cold water damage to rice in accordance with the installation of buried drain pipes in the mountainous areas of the valley. Field research was conducted in order to identify and analyze relevance of cold water damage to rice with underground drain pipe installation. In conclusion, water temperature was analyzed by 0.5 to 4.5℃ lower than before the installation of underground drain pipes, so the cold water damage to rice was likely to occur at the rice paddy field using cold water passing through the underground drain pipe. Therefore, the rice harvest was estimated to be impossible without appropriate measures of water temperature rise such as use of small unshaded warming basins, before water is applied to fields.
