Abstract:

The most remarkable feature of kulun eco-economic circle in Mu Us Sandy Land is that it takes households as units. Forming the cluster model of kulun eco-economic circle in Mu Us Sandy Land from point to surface. In order to explore its sustainability, it is classified according to the clustering characteristics of Coulomb eco-economic circle, and then the sustainability of different types of Coulomb eco-economic circle is comprehensively evaluated. The results show that there are forest and fruit planting and processing mode, planting and breeding plus chain mode, small-scale planting and breeding mode and lazy management mode in kulun eco-economic circle in Mu Us Sandy Land. The highest comprehensive score of the comprehensive evaluation of sustainability is the planting and breeding plus chain mode (81.6106), followed by the forest and fruit planting and processing mode (63.8506), and the worse are the small-scale planting and breeding mode (46.5691) and lazy management mode (24.8808). The latter two models generally exist in Mu Us Sandy Land, indicating that the overall sustainable level of kulun ecosystem is low. Based on the existing resources, it is necessary to improve the management technical means and decision-making methods, optimize the operation mode of kulun eco-economic circle, improve the ecological production efficiency, and enhance the material circulation and energy transformation function of the system, so as to make all kinds of kulun eco-economic circles develop in the direction of sustainable utilization and promote the sustainability of Mu Us Sandy Land as a whole.

Key words: sustainability, kulun eco-economic circle, Mu Us Sandy Land
