Study On The Development And Utilization Of The Natural Resources In Upstream Areas Of Minjiang River In 1912-1949

The upstream areas of Mingjiang River include five counties, they are Tibetan Songpan , black water, Mao County , Li County and Wenchuan of Qiang automonous prefecture of Aba of today.This area will turn from traditional resource development mode to sustainable development to develop the road soon today, the development and utilization of geographical environment of this area and natural resources is focuses paid close attention to at present. This paper bases on the upstream areas of Mingjiang River during the period of 1912-1949, take three kinds of natural resources, which are natural herb, forest reserves and mineral resources, as an example, make preliminary discussion to study to the development and utilization situation of the upstream areas natural resources in Mingjiang River during 1912-1949.The upstream areas of Mingjiang River are located out of the way during 1912-1949, have gifted natural resources, it was blameless that the government adopted and developed the natural resources to promoted social economic development at that time. The government has positive side to the macro-management in the course of development and utilization of resources, but fail to play a role in protecting the natural resources , maintaining ecological balance.The development of the natural resources, which were in The upstream areas of Mingjiang River during 1912-1949, had promoted the development of social economy in this area to a certain extent. It offered a large number of raw materials needed in economic construction for more developed area, such as Chengdu, at the same time. Local people spontaneous to excavate natural herb was the main utilization form, and he natural herb were purchased by the pharmacist and transported to the Guan county o sell. Such management organizations as the medicine canopy , medicine inn ,etc.had appeared in the development and utilization course. This increased the economic income of the Yi people, it was also an important sideline production of the Yi people; The development and utilization of the forest reserves had offered the high-quality raw materials for timber industry and construction. The wooden trader organized workers to cut down the forest. The timber would be tied up and transporting to Guan county by Mingjiang River then sold to every parts of China.There is much gold dust in the upstream areas of Mingjiang River, and the utilization of the gold mine were the core of that of mineral resources, which had prospered the border area. There were a lot of unfavourable factors in the course of development of the natural resources,such as national religious,raffic and geographical climate. The conflict of national interests and private interests may happend. Because of the waste and lack of natural resoutces it caused the ecology to be out-of-balance.The ecological out-of-balance of the upstream areas in Mingjiang River,which was caused by the excessive cevelopment of the natural resources, existed objectively.The disappearance of the forest reserves had caused the local climate to be abnormal, soil erosion, water droughts,etc.The ecological balance was destroyed, which caused many kinds of natural calamity.
