Abstract

Abstract: Rapid industrialization and urbanization have caused serious conflict between humans and nature due to the spatial variability of natural environmental conditions. Integrated environmental zoning (IEZ) is an efficient tool to regulate sustainable development in developing countries such as China. Previous studies explore application of IEZ based on assessment of resource and environmental carrying capacity (RECC) and evaluation of urban development land-use suitability (UDLS). However, existing IEZ oversimplify the complexity of UDLS evaluation, and have low spatial resolution. In addition, it is difficult to express overlay results of RECC and UDLS from a multi-dimensional perspective. Therefore, this study sets forth an improved IEZ by a logic scoring of preference (LSP) and a comparative advantage evaluation. The LSP method and normalized revealed comparative advantage (NRCA) index is applied to assess UDLS and the comparative advantage of RECC (CARECC). The results of IEZ are integrated by overlaying the CARECC zones with numerically processed UDLS maps. A small-scale, rapid development area, Liangjiang New Area (LJNA), serves as the study area. The highly suitable, suitable, moderately suitable, marginally suitable, and not suitable land of LJNA covers 276.60, 368.40, 183.45, 143.22, and 228.33 km 2, respectively. Furthermore, the spatial distribution of RECC in LJNA clearly differ. Based on the results of UDLS and RECC, ten types of integrated environmental zones in the form of "category + intensity" are delineated. The improved IEZ is consistent with the LJNA Master Plan, reflects the logic of human reasoning more accurately, increases the spatial resolution, achieves zoning from multi-dimensional perspectives, restricts the category and determines the sequence of urban development, which can serve as a reference for optimization of land space in LJNA and is also significant to other areas and places. Graphical abstract: Image 1 Highlights: An improved IEZ is proposed based on UDLS and RECC maps. The advantages of LSP and comparative evaluation are combined. The method enable more accurate and multi-dimensional zoning results. UDLS determines the sequence and scale of urban development. CARECC restricts the category of urban development.
