1, Phoenix Ecological Park is located in the transitional zone between the new city and the old city in the south of Kaiyuan City, with a prominent geographical position, which is the central hinterland of Kaiyuan City. The comprehensive construction of forests, lakes and wetlands in Phoenix Ecological Park is organically combined with urban development and construction, and is an important part of urban complex ecosystem. Phoenix Mountain, Phoenix Lake and Phoenix Wetland constitute "one mountain, one lake and one wetland". Being in the Phoenix Ecological Park makes people "see the mountains, see the water, and remember to stay homesick". In the process of promoting the construction of the park, Kaiyuan adheres to the requirements of "high starting point, high standard, all-round and full coverage", and plans the overall urbanization project of Phoenix Ecological Park from a high starting point with the concept of integration of industry, city and humanities to create a scenic spot with beautiful scenery and pleasant scenery. Through the construction of Phoenix Ecological Park, the construction of ecological civilization is the guide.
2. Nandong Scenic Area is located at the south of the city 10 km. It is the first of the eight ancient scenic spots, and it is said that "Longyou South Cave" was discovered in the Ming Dynasty. The Travels of Zhou Zhi Dong Nan, an Ami, says: "The vines at the mouth of the cave are like pale pythons, crossing its door", "The Dan rock is green and beautiful, birds are singing and fish are swimming, and the dust is exhausted". Yang Shengan, the top scholar of Shu people in the Ming Dynasty, once traveled here, intoxicated by the scenery before him, and wrote the word "South Cave" by himself. 1574, Zou Yinglong, the governor of Yunnan, changed his name to "psychic", leaving poems such as "Nan Dongkou" and "psychic". Nandong Scenic Area is a typical karst landform, which consists of eight caves of different sizes, four of which are connected, the most famous being Taoyuan Cave and Tongling Cave. By 2008, Taoyuan Cave will be open only to tourists. South Cave integrates mountains, water, rocks, caves and trees, with 59 scenic spots. Natural scenery and human landscape are in perfect harmony, and each has its own characteristics, such as heroism, danger, strangeness, elegance and beauty. It is a good place for summer vacation and leisure.
3. Yunnan-Vietnam Railway (Yunnan Section) was completed on 1903 and opened to traffic on 19 10. It is the third railway in China and one of the most influential railway projects in the history of railway construction in China and even in the world. Even today, it is still the most precious living cultural relic, living specimen and living fossil in the railway development history of China and even the world. The gauge of Yunnan-Vietnam Railway is 1 m, which is 43.5 cm narrower than the current standard gauge in China, so it is also called "meter gauge" and is the longest existing meter gauge in China. The total length is 854 kilometers, including 465 kilometers in Yunnan (also known as Kunhe Railway) and 389 kilometers in Vietnam. However, the project in Yunnan is much more complicated than that in Vietnam, and the cost paid is incomparable. On the route with only 465km, it crosses Jinsha River, Pearl River and Red River, crosses three climatic zones, namely subtropical plateau monsoon climate, south subtropical semi-humid climate and tropical mountain monsoon rain forest humid climate, and crosses 12 ethnic minority settlement.
