Abstract:

Desertification is one of serious environmental issues in northern China, and decades of the desertification prevention and control have obtained abundant experiences and various models for restoration and utilization of desertified land. With the in-depth enhancement of ecological civilization construction, especially green development, it is urgent to integrate previous ecological restoration technologies and sand industry models of desertified land and evaluate their applicability in the current context. In this paper, firstly 9 models in total are integrated, including engineering and biological desertification control technologies and sand industry models. Secondly their application criteria are formulated in terms of both natural and anthropogenic factors such as meteorological conditions, treatment urgency, transportation convenience, and desertification degree. Finally, taking desertified land and desert fringe areas in the northwest arid region as the study area, the implementation applicability of each ecological restoration and sand industry model in different natural units (natural sandy land and degraded sandy land) and administrative counties is assessed with multi-source data such as remote sensing products, meteorological observations and ground surveys. This study provides technical models, assessment criteria and suitable range for the ecological restoration techniques and sand industries in desertified land, and at the same time provides scientific support for decision makers in formulating restoration and utilization measures for desertified land.

Key words: northwest arid region, desertified land, ecological restoration technology, sand industry, applicability
