The present disclosure provides a method of systematic protection and utilization of hill resources, and relates to the field of protection and utilization of hill resources. The method of systematic protection and utilization method of the hill resources comprises a hill resource protection method and a hill resource utilization method. The hill resource protection method comprises a prevention and control method for geological disasters such as landslide, debris flow, water and soil loss, fire disasters and/or desertification caused by earthquakes, rainstorms and/or drought and the like, and a prevention and control method for continuous weathering of mountain rocks; and the hill resource utilization method is a method for utilizing available resources generated based on the protection. According to the method of systematic protection and utilization for hill resources, a foundation for utilizing the hill resources is built by protecting the hill resources, with protection and utilization integrated. Compared with existing methods, the method provided by the present disclosure not only can prevent and control natural disasters, protect the hill resources and prevent water and soil loss, but also can efficiently utilize water and soil resources, increase the output value, relieve the cultivated land pressure and promote industrial layout adjustment.

A system for flood water or water flow mitigation includes at least one aqueduct or drain having a first section linking a river, lake, reservoir, water retention pond or dam to another section linked to another lake, reservoir, storage tank or sea, characterized in that the first section are positioned at higher than the other section, and the aqueducts or drains are configured to be placed above ground level or extend upward from sides of river or existing drain, such that invert levels of the aqueducts or drains are higher than sea levels during high tide flooding or sea level increases.

A coating film capable of being peeled off in the shape of sheet to facilitate a coating film removal work, and is less likely to peel even after long periods of use on an underwater structure is provided. The coating film comprises an undercoat layer to be bonded to an underwater structure, and an antifouling layer bonded to the undercoat layer, wherein: a 100-gram underwater constant load peeling degree of the coating film is less than 5; a ratio of a tensile breaking strength of the coating film to an adhesive force of the coating film with respect to the underwater structure, as measured after immersing the coating film in pure water at 60° C. for 5 weeks is 1.5 or more; and a 1-mm square cross-cut stretching-caused peeling degree of the antifouling layer with respect to the undercoat layer is 0.05 or less.
