WATER ENVIRONMENT ANALYSIS
XINYUNHE is an east-west river that runs through Pingdingshan City. It was initially excavated as a man-made canal for navigation. Later, due to the development of land transportation in the city, the demand for navigation greatly decreased, and the riverbanks gradually became ecological. However, it is still not connected to the surrounding water systems, which results in poor flood reduction capacity of the river and excessive suspended solids.

Due to heavy seasonal rains and the destruction of natural ecological substrates through urban development, local residents suffer from seasonal canal flooding and water pollution. Through the remediation of river sediment pollution and the restoration of river morphology, I aim to restore the ecological environment of the river and maximize its natural ability to regulate water. To address seasonal flooding, I propose incorporating quasi-natural sunken green spaces for water storage and establishing a slow traffic system and open spaces to reconnect urban water bodies with seasonal river landscapes. This will create a harmonious relationship between humans and nature and enhance the quality of everyone's living space.

Ganjingzi Lime Mine was built in 1929 and is a large open-pit mine. Due to the decline of the mining industry, local economic development has reached a stalemate. The dust and noise pollution caused by exposed mine pits not only affects the lives of surrounding residents, but also causes damage to nearby vegetation, greatly deteriorating the ecological environment of the region.
The long-term rainwater runoff and spring water in the abandoned mine pits have accumulated water at the bottom, thus forming a natural pool. In order to cope with the complex terrain, during the design process, we first established a 3D model of the terrain to assist in terrain restoration, and then made a physical model to refine the architecture and activity space.
The project proposes a sustainable and effective ecological purification strategy. First, it carries out preliminary ecological restoration through artificial terrain restoration and planting pioneer plants; secondly, it completes wateroriented landscape design and architectural design to lay the foundation for the development of the tourism industry, and finally completes Upgrading of local industries.
At the same time, some mining ruins are preserved on the site as a pit theater and pit garden, inspiring people to think about the harmonious development of industry and nature, as well as the possibility of development in the post-industrial era.
REGIONAL BACKGROUND: From
Ganjingzi Limestone Mine was established in 1929 and is a large open-pit mine with abundant non-metallic mineral resources, including limestone and silica, with an annual mining volume of 3 million tons. After reaching its peak economic output, the annual output has declined.
LOCATION ANALYSIS
The mine pit, which is about 2,000 meters long, 800 meters wide, 100 meters high in elevation difference, and covers an area of about 140 hectares, has become the most significant source of pollution in Dalian city.

TERRAIN ANALYSIS
a) The southwest-facing slope is densely vegetated and can provide plenty of shade in the summer.
b) The south-facing slope is the most valuable area for development and planting. If there is a mountain or lake view, it should be maximized under the premise of protecting the ecology.
Residentia
Slope And Orientation
to Urban Scar
The lack of effective protection measures led to the deterioration of the surrounding ecological environment. It formed a giant pit with a length of about 2,600 meters from east to west, a width of about 600 meters from north to south, and a depth of nearly 50 meters. The mine was closed in 2015, and the bottom began to accumulate water.
al area
a) A slope of 15%-40% is suitable for development o ensure soil stability for planting.
b) Slopes greater than 40% are not suitable for development.
c) Slopes less than 40% should be moderately developed.
Hydrological Condition
a) Spring water: This is the largest water system and can effectively reduce pollution entering Tai Ping Lake.
b) Rainwater: Rainwater will directly enter the site, so rainwater treatment is recommended.
a) The analysis results of the developable area show that steep slopes are a constraint on the site. The development area should have a slope of less than 40% and be located at least 10 meters away from the river buffer zone.

Restore the current geomorphology by using slope reduction methods to transform most steep areas into gentle slopes, as well as using existing accumulated materials to achieve excavation and filling balance while preserving some unique geomorphological features.
Based on the current water accumulation at the bottom of the pit, adopt a water-guided landscape design that can also accommodate rainwater from nearby areas.
Restore the ecological foundation by utilizing the secondary succession of plants towards a positive ecological cycle mechanism, which can also ensure the stability of geomorphological restoration through plant growth.
To address economic difficulties after closing the mine, introduce related industries to promote sustainable development of the environment through economic growth.

The front side consists of abundant groups of plants, while the back side is a fastgrowing forest area. The two areas are divided by shrubs.
Grassland - Sparse forest
Located in areas with poor lighting, the front side is an open grassland, while the back side is a space with sparse forest. The overall density is low, leaving space for plant growth.

SITE ANALYSIS
This project is designed to be located on the outskirts of Hohhot, a city once renowned for its livestock farming. The project site used to be a 484-hectare ranch and abandoned meadow.
My goal is to keep the original site function while creating more activity spaces so that the venue can be economically profitable and effective as a large-scale country park in providing entertainment space for local residents, ultimately turning it into a productive and exemplary landscape.
The plan focuses on readjusting the ecological system of the land parcel. I provide a detailed development strategy aimed at creating a fertile, productive, and experiential site, meanwhile establishing a sustainable production model for animal husbandry and agriculture that embodies cultural heritage and improve its ecological service mode.
Nomadic people originated from here
Between the Ming and Qing dynasties, sedentary pastoralism became the predominant lifestyle.
During the Qing dynasty, urbanization advanced.
Then, since the founding of the People's Republic of China, the government has promoted new policies for restoring farmland to forests in search of new modes of ecological ranching.
