mountain
It is surrounded by flat ground on the ground
A raised geomorphic area with large absolute and relative heights
The height of the mountain is usually more than 100 meters above the ground
Including low mountains, mid-mountains and high mountains
But whether it’s called "mountain" or not depends on what the locals call it
Therefore
Xiao Kunshan, which is only 53.8 meters high
Also a member of the "Mountain" family
A bird’s-eye view of Xiaokunshan Mountain
The terrain is low and flat
The maximum relative elevation difference is about 2 meters
It is in the east and the northwest
The trend of low middle and southwest films
The mountain is completely covered by lush vegetation
Full of life
Baidu: Elevation refers to the distance from a certain point in the direction of the plumb line to the absolute base surface, called absolute elevation, referred to as elevation.
So how did the small and exquisite Little Kunshan come into being?
Who gave birth to it?
And how did it give birth to the greenness of life?

The birth of Xiao Kunshan
Late Mesozoic, 70 million years ago
With the Cretaceous Yanshan Movement
Magma along the crustal fault line northwest of Songjiang
gush out of the surface
After long-term weathering and solidification into mountains
When the mountains in future generations have names
According to Ming Zhengde’s "Songjiang Mansion"
All the mountains in the mansion come from Hangtianmu
It has been proven to be true
Xiaokunshan is the remnant of Tianmu Mountain in Zhejiang
It is an earlier area in Shanghai
The ruins of Tangcun Temple and Yaojiaguan are 5,000 years old
Witness the long history of Xiaokunshan
Speaking of the name of Xiao Kunshan
The word "small" is not due to the low altitude and small mountain
The original Little Kunshan name Kunshan
There is also another name for Yushan.
Lu Rong’s "Miscellaneous Notes on Makeup Garden" records:
Kunshan is in the Huating border of Songjiang
The Jinluji brothers gave birth to it
All have literature
Time and People Compared to Kungang Jade
The first year of Emperor Wu of Liang (335)
Kunshan County (because of the territory of Kunshan, hence the name).
Tang Tianbao established Huating County in 751.
Kunshan County was moved to Ma’anshan (now Kunshan City, Jiangsu Province).
At that time, in order to avoid the trouble of two Kunshan duplications,
So before Kunshan, the word "small" was crowned to distinguish,
The name of Xiaokunshan originated from this.

Xiaokunshan is full of treasures
The Xiaokunshan mountain body is mainly composed of Mesozoic lava and pyroclastic stone bodies, mainly composed of granite, granite, chu gray stone and normal rock.
The rocks contained a small amount of pyrite, a brass-colored tetragonal particulate mineralization.
This pyrite (FeS2) is often mistaken for gold due to its light brass color and bright metallic luster, so it is also known as "fool’s gold". It is a very cheap ancient gem.
In addition to being used for grinding gemstones, it can also be used as a base for jewelry, jade, and other handicrafts.
Although Little Kunshan does not produce pyrite, its rich internal resources are a natural wealth that cannot be ignored.

The Birth of Xiaokunshan
Xiaokunshan is located in the west of the ancient coastline and the lower reaches of Taihu Lake Basin, which is one of the lowest areas in Shanghai.
The ocean and rivers and lakes carry sediment and sediment into lake floodplain and lake floodplain, with a thickness of about 300 meters.
Encyclopedia: Lake floodplain facies and tidal floodplain facies are the names of sedimentary facies. Sedimentary facies are the sum of the formation environment, formation conditions, and characteristics of sediments. Rocks with the same composition form the same facies, and those in the same geographical area form the same group.
The wetness of the ocean and rivers and lakes makes the land fertile in the territory. The main parent materials are lake sediments, mainly yellow mud, black mud, blue-purple mud and ditch dry mud. It provides unique and favorable conditions for the growth of crops.
The surface of Xiaokunshan mountain is permeated soil layer, mainly distributed in the western mountainside of the mountain. The depth of the soil layer is between 30 and -50 cm, and the soil is yellow-brown and viscous.
The soil of the hill belongs to zonal acidic soil, which is suitable for the growth of evergreen broad-leaved forest or mixed evergreen and deciduous forest. This makes Xiaokunshan evergreen in all seasons and pleasant scenery.
