It is planned to construct ecological wetland and shoal
rehabilitation works in the reasonable utilization area of
Gaoxuan Village, and to restore wetland in shrubbery,
thick growth of grass, and shoal. The project will take in
waste r from Mianjiang River, and purify the waste r up to
the quality standard of this river section. The ecological

or several kinds of plants as dominant species, plant them in pairs or groups, and
arrange the spatial and time distribution as per certain proportion according to the
characteristics of ambient conditions and phytocoenosis, in order to meet the
requirements of high-efficiency operation and stable & sustainable utilization of
ecological system.
4 Environmental Codes of Practice for Construction Period
4.1 Site Arrangement and Temporary Facilities Construction
(1) Wetland protection and rehabilitation works shall be arranged reasonably and
compactly according to the functional and process requirements of artificial wetland,
by making the best of the beneficial conditions of natural environment, considering
the landscape function of constructed wetland in the project area as well as the

4.2 Surface Waste r Environment Quality Management
During the construction of wetland protection and rehabilitation works, the main
factors affecting the surface waste r are the construction camp, building materials
storage yard, construction personnel’s domestic sewage, waste oil from construction,
and soil loss, etc. Aiming at the abovementioned influential factors, the paper brings
3
Jiangxi Ruijin
Environmental Codes of Practice for Wetland Protection and Rehabilitation
forward the following drainage control measures:
(1) Construction camp and building materials storage yard, etc. must built up possibly
away from surface waste r bodies like wetland, etc., and common building materials
that must be stacked temporarily nearby waste r bodies actually upon the demand of
works construction must be protected with a cover and enclosure.

this paper brings forward the following discharge control measures: Construction
garbage and domestic solid waste shall not be thrown away at random or poured into
waste r bodies along the line, but must be collected and disposed periodically by
environmental protection department.
4.4 Ecological Resources Protection and Management
The main works of wetland protection and rehabilitation is to arrange floating plants,
floating-leaved plants, submerged plants and emergent aquatic plants, etc. in newly constructed
natural ecological wetland, in order to ensure a vegetation coverage ratio of at least 70% of the
ecological wetland protection and rehabilitation works. The main factors affecting
ecological resources include the selection of species, the planting time of vegetation,
and the planting density, etc. The main measures taken include:
(1) The design of wetland protection and rehabilitation works shall increase the
diversity of plants, raise their performance of sewage treatment, and extend their
service life at the largest degree.
(2) The planting soil for wetland protection and rehabilitation works shall be of clay～
doras and 20cm ～ 40cm in thickness, and have a permeation efficiency of
