Tell me what you think of the terrain and climate types in your hometown (my family is in Shaoxing, Zhejiang). I hope it will be handed in soon. It will be handed in tomorrow. Thank you.

Climate:

The city is located in the transition zone between the mid- and north subtropical monsoon climates. It has a significant monsoon climate, four distinct seasons, abundant rainfall, abundant sunshine, and mild and humid climate. The "three major basins" each have their own climate characteristics and are rich in local microclimate resources, but floods, droughts, and low-temperature chilling damage often occur.

The city’s annual average temperature is 16.5℃, the extreme maximum temperature is 39.5℃, the extreme minimum temperature is -10.1℃, the active accumulated temperature ≥10℃ is above 5200℃, 80% guarantee rate is above 4800℃, the daily average Temperatures stably pass the early daily average of 10°C in early to mid-April.

The first frost generally appears in late mid-November, and the last frost generally appears in early late March. The average annual frost-free period is 238 days.

The annual precipitation averages 1438.9 mm and is unevenly distributed. The annual precipitation changes are bimodal with large inter-annual changes, that is, there are two rainy seasons from March to June and September, and from July to There are two less rainy seasons from August and October to February of the following year. The difference between the maximum annual precipitation and the minimum annual precipitation is 895.2 mm; the average number of annual precipitation days is 156.2 days.

The average annual sunshine hours is 1895.0 hours; the annual sunshine percentage is 42.5%

Topography:

Shaoxing is located in the south of Hangzhou Bay and at the northern foot of Kuaiji Mountain. North latitude 29°42′02″～30°19′15″, east longitude 120°16′55″～120°46′39″, 46.6 kilometers wide from east to west, 68.5 kilometers long from north to south, and 356***** kilometers long in perimeter. The total area is 149***** square kilometers.

The tail end of the Kuaiji Mountains in the low mountainous and hilly valley area in the southwest is divided into two branches, extending into the south and west of the county in the southwest-northeast direction, forming a rugged low mountain, hilly and river valley land with an area of ??757** *** square kilometers, accounting for 50.76% of the county’s total area. The mountains in the area are continuous and dangerous, the mountains are uplifted strongly, the terrain is deep and broken, and the water system is short and fast. The general altitude is between 300 and 400 meters, with the highest at Luojiajian at 747 meters. It extends to about 5 to 10 kilometers south of the Xiao-Ningbo Railway, and the height drops to about 20 meters above sea level. It is connected to numerous alluvial fans and the central and northern alluvial plains. , the slopes are mainly 15°~25° and greater than 25°. The landform types are complex and can be divided into four types: valleys between hills, low hills, high hills and low mountains. They mainly include Xialu, Xingtang, Lizhu, Lanting, Pingshui, Shixie and Xiaoshunjiang River Valley, Wangtan and Pingshui basins. Such valleys and basins have smaller areas, narrower mountains, turbulent water flow, higher gravel content, and obvious soil alluvial. There are large areas of slopes and terraces at the junction with the Shuiwang Plain, especially in the areas of Lizhu, Lanting, Nanchi, Potang, Jiuli and Shangjiang. The slopes are all below 10°, and the soil is deep, suitable for farming. There were frequent agricultural reclamation activities in the Neolithic Age, and most of it is now used as planting land for tea, mulberry, fruit and other cash crops and dry grain land, occupying an important position in Shaoxing's agricultural history.

The water network plain area in the north-central part covers an area of ??572***** square kilometers, accounting for 38.33% of the total area of ??the county. Except for scattered igneous rock residual hills, they are all formed by alluvial, siltation and marine accumulation. The terrain is flat, with an average altitude of 6 to 7 meters. There are occasional isolated hills and the height of the remaining hills generally does not exceed 200 meters. In the central part, there are crisscrossing rivers, scattered lakes, and farmland cut into large and small fertile fields. It is known as the "Water Country". Close to the narrow strip in the north of the ancient seawater, the terrain is low and flat, with an average altitude of 4.5 meters. There are few rivers and the water surface is narrow. It is a transition zone to the coastal beach. Historically known as Shanhui Plain, it was originally a shallow swamp with tides. The global post-glacial period was flooded by sea water. 6,000 years ago, Lizhu and Pingshui were the junctions of hills and coasts directly exposed to sea water.

Around the 21st century BC, the sea began to recede and the coast moved northward. At the end of the sea recession, the coastline profile has become similar to that of modern times. Due to the rich source of sediment, the drowned valley is shallow and blocked, and the shallow sea gradually rises and turns into a Juyi swamp infested by salt tides. "Guanzi Shuidi" states that "the water in Yue is heavy and turbid, so its people are stupid and sick." dirt". Around 3000 years ago, Yue residents moved north from the interior of the Kuaiji Mountains and began to colonize the alluvial fans at the foot of the mountains and some larger isolated hills and nearby slopes in the plains that were beyond the reach of the salt tide, thus forming the central alluvial plain.

At the beginning of the 5th century BC, the State of Yue moved its capital from the southern part of Kuaiji Mountain to the swampy plain. It built the northern foot of Kuaiji Mountain through dikes, ponds, salt rejection, and freshwater storage similar to modern reclamation of tidal flats. There is a large amount of cultivated land below the alluvial fan.

During the Qin and Han Dynasties, northerners moved southward and the development of lakes and swamps accelerated. By the middle of the 2nd century AD, Jianhu Lake was built, and 9,000 hectares of fertile farmland were opened below the lake. Seawall construction and river and lake network improvements have also been accelerated. In the second year of Chuigong of the Tang Dynasty (686), the 50-mile boundary pond between Shanyin and Xiaoshan was built; in the tenth year of Kaiyuan (72****), Li Junzhi, the magistrate of Kuaiji County, presided over the addition of the Shanhui seawall. Later, in the tenth year of Dali (77** It was not until the sixth year of Yamato in Japan (83) that the Fanghaiwall was formed, starting from Shangyu in the east and ending at Shanyin in the west, with a total length of more than 100 miles, and the Shanhui Plain was fully formed. To this day, the water network plain in the central and northern parts of the country is Among the 610 natural villages, 226 are named after rivers, lakes, dais, bridges, rivers, villas, ponds, ponds, weirs, banks, harbors, and pu, etc., accounting for 34%, showing the specific landscape of the water town.

The northeastern coastal plain area has a flat terrain, criss-crossed by artificial water systems, and an altitude of about 5 meters. The total area of ??the area is 162***** square kilometers, accounting for 10.91% of the total area of ??the county, and 67.4% of it has been reclaimed. The supratidal zone or intertidal zone has yet to be developed. The north bank was continuously eroded by the tides of the Qiantang River and the Cao'e River, and the south bank gradually silted up from Yongle to Wanli in the Ming Dynasty (1403-1620). After the land was moved, the tidal flats in Shanhui and Shanhui counties began to recede spontaneously, and people planted cotton, melons, beans and rice. During the Xianfeng period of the Qing Dynasty (1851-186), it became the Qian and Kun sandy lands in the west of Sanjiangkou, covering an area of ??100,000 square meters. More than 40,000 acres. At the end of the Qing Dynasty and the beginning of the Republic of China, the tidal flats once stretched for more than 20 miles to Hangzhou Bay, and there were reclamation areas such as Mopanqiu and Tofufan. After that, due to the migration of the Qiantang River's southern trough, large areas of the tidal flats collapsed and were completely lost in 1969. Organized large-scale artificial reclamation of land began in 1991. By 1991, 10 reclamations had been carried out, and 66.3 square kilometers of land had been acquired (from October 1993 to April 1994, the first phase of "Jiu Sanqiu" reclamation acquired 8.7 square kilometers of land. square kilometers (not included), there is a coastal plain, and the stepped landform of mountains, plains and coasts from south to north is established.
