| The temporal -spatial analysis on the agricultural management pattern can help us to understand the mechanism of the changes about modern agriculture. By using gross output value of farming, forestry, animal husbandry and fishery data of Guangdong in 1990 to 2012, the gravity center model was established, from which we could analyze temporal -spatial evolution of the gravity center of agricultural economic and the distribution of the main agricultural products. The results showed that from 1990 to 2012, the center-of-gravity of agricultural management pattern moved towards southwest. The movement of farming, animal husbandry and fishery was more obvious. Spatial concentration of main agricultural products increased. At the same time, west wing of Guangdong province progressively became predominance area of regional specialized production. It爷s concluded that natural resource endowments, social and economic growth, technological innovation were the main driving forces, and social and economic growth, technological innovation played a more important role. |
