Abstract [Background] In recent years, with the development of regional social economy, production and construction projects are increasing day by day. The phenomenon of soil erosion caused by production and construction projects is becoming more and more serious. In order to strengthen overall supervision of production and construction projects, to effectively curb man-made soil erosion, and to ensure the sustainable development of regional ecological environment and social economy, this paper takes Huoqiu county in Anhui province as the research area and explores the spatial-temporal distribution and compliance analysis and evaluation of disturbance pattern spots in production and construction projects.[Methods]Using multi-source data, combined with ArcGIS platform, UAV aerial photography, field survey and other technical means, the disturbance pattern features of production and construction projects in the region were explored.[Results]1)From 2015 to 2016, there were 780 disturbance patches of production and construction projects with an area of >0.1 hectares in Huoqiu county, covering a total area of 8 442.14 hectares. Disturbance pattern spots were concentrated in the northwest and southwest of Huoqiu county. The types of production and construction projects were mainly metal ore mining, and the disturbance pattern area of production and construction projects mainly concentrated in 1-5 hm², and the main disturbance change type was the continuation pattern. 2)Houqiu county has approved 20 production and construction projects. Well mining Metai ore accounted for 70% of the approved projects. The scope of responsibility for prevention and control of approved production and construction projects involved 51 map spots, among which 12 were in compliance, and the main type was well mining metal ore. There were 39 non-compliant spots, including 16 that were suspected to have changed construction sites, and 23 that were suspected to be beyond the scope of responsibility for prevention and treatment. 3)In Huoqiu county, 580 suspected unapproved map spots with an area of more than 1 hectare accounted for 88.68% of the total number. Most of the projects were not implemented in the production and construction activities, but also highlighted the lack of local supervision and other issues.[Conclusions]The situation and task of water administration department's supervision and management is severe. It is still necessary to strengthen the precise supervision and management of production and construction projects to effectively curb man-made soil erosion.
