油茶是世界四大木本食用油料植物之一，生态效益和经济效益俱佳。常宁市自然地理条件适应种植油茶，种植油茶历史悠久，全市各乡镇都有分布，以东北部的烟洲镇、荫田镇和蓬塘乡的种植面积最大，均在4000h秆以上。其外围乡镇油茶种植面积次之。自新中国成立以来，常宁市的油茶种植面积的变化大约分为三个时期。新中国成立至80年代中期，油茶种植面积持续增加；80年代中期至90年代初期，是老林更新改造时期，成林面积减少；90年代中期以来，油茶种植面积稳步增长。今后应增加科技投入，实现常宁油茶的可持续发展。

Oil-tea camellia is one of the four woody edible oil plants in the word, and it has good ecological and economic benefits. The natural geographical conditions of Changning City adapted to cultivate oil-tea camellia. The city has a long planting history and it distributed in all townships,but the largest areas located in the North-east townships of Yanzhou,Yintian and Pengtang. The average areas are above 400 hectares and its surrounding towns followed. Since the founding of new China, the evolution of the planting areas can be roughly divided into three periods. From the founding of the new China to the mid of 1980＇s,the plant- ing areas continued to increase, from the mid of 1980＇s to the early of 1990＇s,it is a period of renovation of Old Forest and the forest area reduced,and since the mid of 1990＇s, the planting area gradually grew. The investment in science and technology should be increased in the future to achieve the sustainable development of oil-tea camellia in Changning.
