| Abstract: |
| Most coastal cities in China have experienced extensive “savage growth” in their
tortuous land reclamation process, and now the land reclamation area has been gradually
saturated. However, due to the dislocation of land development in the past, the planning of
reclamation area’s green space system is infl uenced by many factors from land and sea aspects,
which makes it signifi cantly different from the ordinary inland area and riverside area’s green
space system. Reclamation methods and maritime boundaries limit the function of green space
system for limited scale, and structure and location end lead to the lack of green space system
open sharing, Saline-alkali land, water quality, climate and other natural conditions of ecological
green space system instability, sea and land of two-way disasters seriously damaging highlight
the four types of green space system comprehensive disaster prevention ability insufficient,
therefore, based on the existing studies of many scholars and the current status of China’s inland
urban planning that has entered the stock restoration stage, landfi ll for the above four aspects:
problems of area green space system, creatively puts forward the strategy of using the existing
land to repair the existing green space system in the reclamation area.
Due to the policy, social, economic and geological conditions and other reasons, the land
in the reclamation area has been in a state of inefficient utilization. Some land has been in a
state of non-use for a long time, among which the non-use state includes the vacant land and
abandoned land in the developed land. These large and scattered land stocks, some of which
have poor location conditions and low economic utilization value, are suitable for reactivation,
land structure adjustment, improvement of the present situation of reclamation greening system,
and improvement of its sustainability. We will re-evaluate the value of social, economic and
ecological use of these unused land, and establish a “green land storage bank”. On the basis of
clarifying the ownership information, it carries out hierarchical management, and evaluates the
existing land in the reclamation area from four aspects: function, scale, location, and ecology
and disaster prevention. On “green land storage bank” stock of each piece of land for strategic
target classifi cation, classifi cation standard according to solve the problem of present situation of
green space system in four types, proposed four repair applicable strategies for qualitative and
quantitative evaluation: “supplement”—complement reclamation area green space system scale
discrete breakpoints, improve its sustainability, “adjustment”—adjust the green space around the local land function layout, implement green open sharing, “replacement”—serious Saline-alkali land replacement, improve biodiversity, “augment”
green space system, increase industrial agglomeration area green space, restore land nature, strengthen regional disaster prevention repaired four
different coping strategies. Proposed on the basis of the above criteria for “green land storage bank” stock of land for composite evaluation score,
by satellite image map reclamation area green space system present situation, after number on each piece of green space to store the corresponding
stock of “green land storage bank”, the green space system on the floor plan to repair on classified summary, summarized four types of green space
system plan of the grayscale composite respectively with four applicable strategies, choose the most suitable way of repair and the corresponding
repairing block position. Then, on the basis of the existing study on sustainability index selection principle, combining with the actual case problems
of four types of green space system, through the index weight, select and scale continuity, social sharing, ecological sensitivity and comprehensive
disaster prevention of related 12 indexes, the study sets up evaluation index system of green space system sustainability. This evaluation system is
based on different scheme of each green space for sustainable factor score or attribute classification, and compares different size layout scheme of
the overall scale of continuity, social sharing, ecological sensitive stability and comprehensive disaster prevention ability to verify whether the repair
of reclamation area green space system achieves sustainable objectives.
Finally, due to the severe phenomenon of soil salinity and less soil resources for green space construction in coastal new-region, the paper takes
reclamation area of Tianjin Binhai New Area as an example, through the summary and analysis of the characteristics of the stock of land property,
organizes and establishes the “green land storage bank”, which chooses the most appropriate method of repairing the stock of green space system
to verify the applicability of the stock land repair strategies, and then uses the stock of land reclamation to fix the present situation of green space
system in coastal new-region by scale continuity repair, social sharing repair, ecological sensitivity repair, and comprehensive disaster prevention
repair respectively. It is hoped that the proposal of this strategy will bring inspiration to solve other problems in coastal new-region’s green space
system. In this way, the fragile ecological environment caused by the reclamation area green space system can be truly alleviated. More attention
should be paid to the sustainable planning of the reclamation area green space system. |
