Overall Planning & Stormwater Wetland Design of Mt. West Country Park BACKGROUND

The site of the country park is located at the eastern foot of Mt. West in Shijiazhuang, Hebei Province, covering an area of 1,311.9 hectares. This hillside area is an intermediate zone between Mt. Taihang and the North China Plain, between urban land and natural forests. Shijiazhuang is a typical city suffering from water shortage, and its uneven seasonal distribution of precipitation leads to frequent floods in summertime. Therefore, the development of this country park on the theme of plant landscape and natural waterscape is challenged by shortage of water resources.

STRATEGY

To better conserve water and soil, we propose to accumulate rainfall catchment at the site to meet with the needs of waterscape and plant irrigation, rather than depending on external water resources. With concepts of low impact development (LID) and temporal and spatial balance strategy, low-lying terrain is designed for natural waterscape and surface runoff in floods is collected by water storage facilities to guarantee the water supply to meet with the needs of the whole park through out the year. Besides, through quantitative research, the recreational service facilities of the country park are upgraded on the basis of waterscape and plant landscape layout planning, and a natural and economical country park planning scheme is formed. Under the guidance of LID concept, the project further selects one of the waterscape display to enrich the design scheme of stormwater wetland landscape through rain and flood management and water quantity calculation.

DESIGN INTRODUCTION

One pond is merged to demonstrate the specific design of stormwater wetland based on the strategy of waterscape in overall planning. Considering both water balance and diverse waterscape all year round, the stormwater wetland is divided into deep section and shallow section in order to adjust the seasonal water level while maintaining the same volume and area of stormwater wetland.

Close-to-nature Urban Forest Design

BACKGROUND

The site of this project was assigned to be constructed into an urban forest as a response to the Call for National Forest City Construction in 'Beijing city master plan from 2016 to 2035'. Faced with environmental pollution and ecological destruction, the project was challenged by how to quantitatively estimate whether an urban forest was natural and how natural it was. Therefore, this project attempted to construct a closeto-nature evaluation system of an urban forest, which was used as a quantitative evaluation system in forestry management, and then verified this system by designing a close-to-nature urban forest.

STRATEGY

A close-to-nature urban forest evaluation system including a calculation table with 5 criterion layers and 18 indexes was established via Analytic Hierarchy Process (AHP). Based on this evaluation system, a new procedure of urban forest design was proposed to create a natural urban environment for all the living beings. The vertical design of the terrain was considered at the first step in order to provide biotopes for forest vegetation.

Secondly, specific native tree species and forest communities were planted chronologically according to the highest level of close-to-nature urban forest evaluation system. Finally, recreational and tourist facilities were designed based on characteristics of different forest biotopes and communities.

BACKGROUND

This project focused on a neighbourhood constructed in the mid and late 20th century in central area of Beijing, which showcased the impact of the rapid economic and urban development in the past three decades. In particular, the original green space of the target community was in low quality and connectivity so that the renewal and redesign became urgent for the improvement of the neighbourhood to match the residential and ecological benefits. We discovered the root cause of the problem faced by this community was the change of its position and function in the center of Beijing city. It used to be an area of workshops and compounds on the city's edge in the early 1960s. However, with the expansion of Beijing city, it became much more central and nowadays residents ask for high quality and high-valued green space and living environment.

Therefore, this project was aimed to motivate potential space and residential quality in old neighborhood by renewing the existing green space and creating a dynamic green space system.

STRATEGY

GREEN+

This project considered the local neighbourhood green space as a whole renewal plan and proposed a redesign with three innovative methods. Firstly, it increased the accessibility of the green space by integrating the existing fragmental public space in the whole neighbourhood. Secondly, it connected each green by creating plant borders along paths which formed an interconnected green network of this neighbourhood, a network similar to human capillaries. Thirdly, potential green space was selected by blending the function of its surrounding land use. Finally, a specific site of potential green space was selected to demonstrate the methods and process of green space design in neighbourhood renewal.

DESIGN INTRODUCTION

Based on the theory of garden-style community, functional superposition method of ecology, recreation residences and businesses were proposed in this neighborhood renewal project. The site was divided into commercial space and green space, which was superimposed by functions of surrounding land use. New commercial and office complexes and community center were designed in the south of the site, fully covered by roof garden in order to meet the demands of surrounding residences.

BACKGROUND

Qiang, Tibetan and Han nationalities have a long history of development in Aba Autonomous Prefecture in Western Sichuan. The project site is located at the intersection of three ethnic settlements. Long-term wars and conflicts among the three peoples in ancient times resulted in differences in production modes and living environments, as well as unfair social problems in regional development such as backward economic development, shortage of resources and inconvenience of transportation in Qiang and Tibetan settlements. At the same time, natural disasters such as landslides and debris flows are also serious problems existing in the social development of agriculture, trade and transportation in this region during the rainy season every year.

STRATEGY

First step, potential landslide zones were marked according to the analysis of steep slope and hydrology with GIS. Secondly, special retaining walls which could hold falling earth and rain streams during the landslide were designed and built in these potential landslide zones. Thirdly, potential landslide zones were gradually transformed into rice terraces and fishponds, which were suitable for the most special local mode of agricultural production. Previous disaster zones were transformed into basic zones of the social production with the cooperation of natural force and artificial constructions built by local people in three different nationalities.

One side of the retaining wall is a pond of water, which is used to raise fish and accumulate fertilizer. Relying on the walls, people can set up roads to promote logistics.

Retaining walls are connected with each other, with the roads developing, the number of terraces are increasing, and the original fertilizer is used to grow crops.

Cultivated land, fertilized ponds become more and gradually form the system, which further promoted the three peoples’Trade communication.

As a landscape architect, it is my duty to maintain the balance between human and nature as long as possible.
