| 摘要: | Forming the boundary between Miaoli Hsien and Taichung Hsien, the Taan River flows some 96 kilometers from its eastern origin with 3296 meters above sea level in the western slope of Ta-pa-chian-than into Taiwan Strait. Although it is not the longest river in Taiwan, it plays a major geographic role.
To the south of the upper Taan River lies Hsuehshan (Snow Mountain). With high ranges running. generally: northeast to southwest for forty kilometers, Hsuehshan Mountains are able to stop in winter the strong northeast monsoon with a heavy rainfall The winter climate in western Taiwan Is as a result divided by these mountains into two apparently different parts, as is the distribution of crops Hsuehshan Mountains and the Taan River, therefore) may respectively be compared to Ching Ling and the Huai River which divide China into two parts geographically.
Owing to its rugged and varied relief the basin is a complex of many sub-geographical units of climate, topography, soil agriculture, etc.
Only one fifth of this basin belongs, to alluvial plain: Known as Tachia plain. The rest are hilly regions. Most of the population concentrate' on the alluvial plain; the average density of population is roughly 800 to a square kilometer. A few of them scatter along the river terraces where waters and farm lands are available.
By 1969, the basin's population had grown to 230,000; of them more than sixty percent are farmers. In other words, agriculture is still the prevailing occupation of the inhabitants. Many kinds of crops are produced but the flatter the land is the fewer kinds of prevailing crops it produces Owing to the lack of farm workers the developement of agriculture is greatly obstructed, only by accelerating the mechanization of farming, can the problem be solved.
China has been founded with its basis on agriculture .Her people seen to have little interest in the cultivation of the hilly, lands which are only a; little, higher, than the flat plains around, them. But, now, the heavy pressure of population, over the intensely cultivated lands is bound to compel the inhabitants to climb up the hills. HOW, then o direct, the inhabitants to use their lard properly so as to maintain its productivity at its best, and how to produce more food to feed a constantly increasing population are discussed in detail in this article. |
