Problems and Countermeasures Facing the Sustainable Development of Yunnan Nujiang Autonomous Prefecture 1 The Strategic Significance of Sustainable Development of the Yunnan Nujiang Basin The Yunnan Nujiang Basin is located in the southwest border of my country, with a main stream length of 624 km in Yunnan Province and a drainage area of ??24,000 km2.

From the perspective of the systematic pattern of my country's major river basins, although the basin is not large in area and has a short main stream in my country and Yunnan Province, its ecological economy and sustainable social development have very important social, economic and political significance. .

(1) The Nujiang River Basin is a typical region in western my country that is rich in resources, has great development potential, but is economically underdeveloped.

In the implementation of the macro-strategy of the Western Development, how to correctly understand the advantages and disadvantages of regional economic development in the Nujiang River Basin, build a regional industrial system that conforms to the local resource environment and socio-economic characteristics, and achieve sustainable development of the basin is not only related to the economic level of the basin itself

It also plays an important role in early exploration and reference for the regional development of other similar areas in the west.

(2) The Nu River is one of my country's 16 important international rivers. The sustainable development of the Nu River Basin is an important project for my country to develop border areas, stabilize and prosper border economies, and build a good international economic environment.

The Nu River originates from Tibet, my country, and is a river in many countries including China, Myanmar and Thailand.

The downstream countries of the Nu River Basin are poor countries with underdeveloped economies in the world, and their economic strength is relatively weak. The ecological environment management and regional development of the Nu River Basin in Yunnan lack good international economic support, and they can only rely mainly on my country's own investment, basin management and development. The difficulty is greater.

However, the development of the Nu River Basin in Yunnan is an important contribution of my country, as a developing country, to the global implementation of sustainable development strategies. The development and management of the river basin also have important international political significance for the ecological and environmental protection of other downstream countries.

(3) The sustainable development of the Nujiang River Basin is a need for my country to implement its anti-poverty strategy.

The Nujiang River Basin is one of the regions with the most backward economic development in my country. It has low agricultural production levels, poor industrial foundation, and a large proportion of poor people. The realization of sustainable development in the Nujiang River Basin is actually an important practice in implementing poverty alleviation projects in poverty-stricken areas in my country. It plays an important and typical role in improving the overall level of our country's national economy and comprehensively improving the quality of people's lives.

(4) The sustainable development of the Nujiang River Basin is the need for my country’s national unity and common development.

The Nujiang River Basin is the birthplace of my country's Lisu, Nu, Dulong, Bai and other ethnic minorities, and is the area on which they depend for survival.

The successful implementation of river basin development will not only promote economic development, improve regional economic quality and people's living standards, but also take into account the inheritance and development of ethnic minority cultures. It has important social significance for maintaining my country's national unity and social stability.

(5) The sustainable development of the Nujiang River Basin is an important part of my country’s implementation of biodiversity protection and sustainable utilization of biological resources.

The Nujiang River Basin is rich in biological resources and has complex and diverse ecological landscapes. It is an important area for global biodiversity and ecological landscape protection.

However, due to the fragile nature of its natural environment, it is difficult to restore it once damaged. In addition, due to the recent overload of the population, the watershed ecosystem is suffering from unprecedented human interference in history. Scientific and reasonable watershed development and protection are urgently needed to achieve sustainable development of the watershed.

So that the precious gene pool of nature can be preserved to the maximum extent.

2 Ecological economic pattern and resource and environmental characteristics of the Nujiang River Basin in Yunnan The Nujiang River Basin in Yunnan is located between 98°07′～100°02′ east longitude and 24°07′～28°23′ north latitude. It is a narrow transition zone from the Qinghai-Tibet Plateau to the Yunnan-Guizhou Plateau.

The administrative division mainly includes 3 counties of Gongshan, Fugong and Lushui in Nujiang Prefecture and 4 counties and cities of Baoshan, Shidian, Longling and Changning in Baoshan Prefecture, with a land area of ??24,000 km2 and a population of 2.012 million.

Accounting for 6. 1% and 4. 8% of Yunnan Province respectively.

The ecological economic pattern and resource and environmental characteristics of the Nujiang River Basin in Yunnan are as follows.

2.1 The natural landscape is diverse, but the regional ecosystem has weak resistance and poor self-recovery function. The Nujiang River Basin in Yunnan is one of the components of the Hengduan Mountains. It is mainly composed of the Gaoligong Mountains, the Nujiang River Valley and the Nujiang Mountains, which are huge and undulating, running from north to south and juxtaposed from east to west.

(Southern Biluo Snow Mountain). The terrain in the basin slopes from northwest to southeast, and the terrain is broken and steep.

According to the differences in geological structure and lithology, the Nujiang River Basin can be divided into three geomorphological sub-regions from north to south: the extremely high mountain canyon area, the high mountain canyon area and the mid-mountain canyon area.

Due to the long-term crustal movement, the fault zones in the basin are fully developed, forming a landscape pattern dominated by mountains, with high and medium mountain canyons and low mountain hills and basins (bazi) arranged alternately.

Among them, mountainous areas account for 97% of the total land area in Nujiang Prefecture, and 91.8% of the total land area in Baoshan area.

Due to the large terrain height difference in the Nujiang River Basin in Yunnan, undulating mountains, deep valleys, fragmented terrain, thin soil layers, and many stones, the regional ecosystem has weak resistance and poor self-recovery function.

Once surface vegetation is destroyed, geological disasters such as mudslides and landslides are very likely to occur, making environmental restoration difficult.
