| Abstract: |
| The land spatial planning of coastal zone is very important in the territorial space
planning system. It plays a key supporting role in straightening out the practical problems such as
the overall planning, coordination, protection and utilization of sea and land space of coastal cities.
At the present stage, some framework results of the territorial space planning have been basically
completed. But based on this planning, the functional cohesion problems of the land and sea have not
been addressed in the counties or districts’ level. And the framework results can’t provide support for
the assessment of the specific function of the sea and land area. There are two aspects of the problem
as below. Firstly, the standards and classifications of the land area and sea area are totally different.
In spite of the consideration of both the land area and sea area in the territorial space planning,
there is no unified evaluation criteria which can resolve the problem of the functional conflicts. The
land use adjustment method to the functional unsuitable area still lacks scientificity. Secondly, the
assessment system is suitable for the natural conservation and not for the urban development. It lacks
of the indicators about the functional development which provide support for the function division.
Functional suitability evaluation is urgent to be established to support the function adjustment of the
coastal zone which includes the sea, the land and the land-sea junction area.
The aim of this research is to provide the evaluation and function adjustment method of the
functional zoning planning. This paper is organized into three part as follows: The first chapter
introduces the frame and the classification of the functional zoning planning. Relying on the
existing standards, the land and sea use types have been reclassified. The second chapter shows
the construction ideas and processing functional suitability evaluation. Multi-type standardization
methods and weight determination methods are comprehensively applied in the evaluation process
to solve the problem of huge differences in multi-type indicators. The third chapter is the adjustment
and optimization method of coastal functional zoning based on land and sea integration. The 3D
Rubik’s Cube model and the cross analysis method in GIS are used to process the evaluation results.
The qualitative method of data collection and induction is used in the decision-making method
of functional conflict. The case of Qinhuangdao City, Hebei Province, is used to introduce the
evaluation process and evaluation methods and runs through each chapter.
The conclusions of the paper are as follows：1）The framework of functional suitability evaluation
is proposed. The “three zones” of land and sea areas can be analyzed in a unified way. The integrated
territorial and spatial function zoning system of coastal zone based on land and sea coordination has been
constructed. In this system, a unified classification standard and evaluation process for land and sea are
proposed. This will help assess the issue of land and sea conflicts; 2) Evaluation indicators are optimized
and supplemented. Based on the indicators of the territorial space planning, the indicators that emphasize
the impact of sea areas, resource assessment and socio-economic development have been further added.
The evaluation index system of sea-land spatial function suitability has been established. And the spatial
suitability zoning method of “agriculture-onstruction-ecology” land function has been proposed; 3)Function zoning optimization method is established. Based on the principle of functional compatibility and conflict adjustment and optimization, the evaluation
results are superimposed with the results of “three line” delimitation and the current land use. As a result, the functional conflicts of sea area, land area and adjacent
areas of sea and land are identified. Further specific adjustment principles have been formulated. The case study of Qinhuangdao City verified the accuracy of
functional conflict identification and the feasibility of adjustment.
The innovation of this research is to establish a new method of functional suitability evaluation. On this basis, the function zoning adjustment process for the
sea-land conflict is proposed, which has been ignored in the current territorial space planning. This resarch is mainly used to link up the preliminary results of the
“three lines” delimitation and the specific functional zoning scheme of the territorial space planning of coastal cities. The balance of evaluation indicators has been
improved. At the same time, the suitability of land and sea functions has been focused on. However, it is worth noting that the data accuracy of the basic evaluation
unit in this research still needs to be improved due to the limited data confidentiality and access issues. Furthermore, on the premise that the method system remains
unchanged, the index selection and weight optimization can be carried out according to the actual situation of different coastal areas. |
