THE CLIMATIC RESOURCE IN THE QINGJIANG RIVER VALLEY AND ITS DEVELOPMENT AND UTILIZATION

This paper discussed the unique climatic resource in the Qingjiang River valley. The features of the climatic resource in the area can be concluded as follows. (1) It is very warm in winter and frost period is short. (2) There are two different heat zones along the river valley, that is, north subtropic and centeral subtopic zones. (3) According to the sea level elevation, the mountain can be divided into several climate zones. (4) Precipitation is even around the whole year and rainfall can be used effectively by crops. In addition, it has been found that both totography and meteorological systems rusult in these features. In order to exploit the climatic resource, we have recommended some crops for the different heat zones. These crops must be: under suitable climate condition,high economic value and great market demand. Therefore, It is suggested that: (1) below the sea level elevation 500 m is suitable for citrus and tung oil tree, (2) tea tree and masson pine could be planted between 500 m and 800 m, (3) mushroom and Chinese chestnut are suitable for the elevation 800 m-1200 m, (4) the land above 1200 m can be used for forage grass and medicinal materials. Finally, the dangers of climatic resource used in this region have also been evaluated in this paper.
