Abstract

This study was conducted to classify agro-climatic zones in Northeast district of China. For agro-climatic zoning, monthly mean temperature and precipitation data from Global Modeling and Assimilation Office (GMAO) of National Aeronautics and Space Administration (NASA, USA) between 1979 and 2010 (http://disc.sci.gsfc.nasa.gov/) were collected. Altitude and vegetation fraction of East Asia from Weather Research and Forecasting (WRF) were also used to classify them. The criteria of agro-climatic classification were altitude (200 m, between 200-800 m, 800 m), vegetation fraction (60%), annual mean temperature ($0^{\circ}C$), temperature in the hottest month ($22^{\circ}C$), and annual precipitation (700 mm). In Northeast district of China, mean annual temperature, annual precipitation, and solar radiation were $3.4^{\circ}C$, 613.2 mm, and $4,414.2MJ/m^2$ between 2009 and 2013, respectively. Twenty-two agro-climatic zones identified in Northeast district of China by metrics classification method, from which the map of agro-climatic zones for Northeast district of China was derived. The results could be useful as information for estimating agro-meteorological characteristics and predicting crop development and crop yield of Northeast district of China as well as those of North Korea.

본 연구에서는 중국의 동북지역 기후자료를 수집하여 DB를 구축하고, 이들 기후자료를 활용하여 농업기후지대를 구분함으로써 대상지역의 농업기상특성 분석의 기초정보를 확보하고자 하였으며, 국외의 주요 곡물 수출국의 기상관측정보를 수집, 분석, 제공할 수 있는 체계를 구축하고자 하였다. 중국 동북지역 농업기후지대를 구분하기 위하여 미국 항공우주국의 전 지구 모델링 및 동화 센터의 1979-2010년까지 32년 동안의 월별 기온 및 강수량 자료와 Weather Research and Forecasting(WRF) 모형의 동아시아 영역의 해발고도와 식물비 자료를 활용하였다. 중국 동북지역은 해발고도는 200m 이하, 200-800m, 800m 이상, 식물비 60%, 연평균 기온은 $0^{\circ}C$, 최난월 기온은 $22^{\circ}C$, 연평균 강수량 700mm를 기준으로 22개 농업기후지대로 구분되었다. 22개 농업기후지대는 연평균기온은 $3.4^{\circ}C$, 강수량 613.2mm, 일사량 $4,414.2MJ/m^2$의 기후특성을 보였다.
