强可持续发展框架下生态空间评价.

Strong sustainable development sticks to the irreplaceability and uniqueness of natural capital and maintains that the essential stock of natural capital should be passed on from one generation to another. It achieves environmental equity and intergenerational equity by maximizing the intertemporal utility of environmental benefits. This paper analyzes the dimensions of the strong sustainable development paradigm in identifying ecological space. The ecological space can be divided into two categories: strong sustainable development space and weak sustainable development space. The former refers to the critical ecological space where ecological security is maintained and the priority is to maintain the status quo of the ecosystem, or at least keep it from sinking into degeneration. In contrast, the latter belongs to the non-critical ecological space, where proper development and construction can be carried out within the ecological security threshold. Based on the case study of the Tarim River Basin and the concept of strong sustainable development, this paper keeps to the method of combining ecological service function and ecological sensitivity in assessment and conducts research on the classification of the ecological space and the patterns of strong and weak sustainability. According to the research, the sensitive and extremely sensitive areas of the Tarim River Basin take up the lion ’s share of the total area, or 55.01% and 29.23%, respectively. The strong sustainable development ecological space incorporates the urgent ecological space and the crisis ecological space, which stand at 305 257.84 km² and 573 281.16 km², respectively, accounting for 29.28% and 54.98% of the researched area, respectively. The re‑ search reveals a high degree of conflict over the ecological security of land use in the Tarim River Basin and a desperate adjustment ca‑ pability for the strong sustainable development of ecological space. Ecological space of strong sustainable development is an important ecological functional space. Accurate identification of ecological space can provide a scientific basis for the delineation of ecological protection red lines and the management of ecological space. Ecological space evaluation based on the paradigm of strong sustainable development can provide green development planning ideas under ecological priority for the subsequent development strategies of respective regions.
