Embodiment Construction

[0037] A clear and complete description will be made below in conjunction with the technical solutions in the embodiments. Apparently, the described embodiments are only some examples of the present invention, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] In this example, aiming at the land use pattern, the optimization and upgrading of agricultural industry, and the environmental effects of agricultural development under the conditions of rapid urbanization in the Dianchi Lake Basin in Yunnan, a new urban agricultural non-point source pollution reduction technology was developed in the Baoxiang River Basin.

[0039] First of all, the background of urban new agriculture in this area is investigated and classified according to the types of large-scale agricultural industries, and the area is ...

Abstract

The invention relates to a classification-type comprehensive prevention and control method for urban agricultural non-point source pollution, and belongs to the field of ecological agriculture. The method includes the following steps: step (1), according to different large-scale industry types appearing in an agricultural production mode of a region, the region is divided into three agricultural industry types: facility agriculture, urban nurseries and urban orchards; step (2), prevention and control aiming at the facility agriculture are performed; step (3), prevention and control aiming at the urban nurseries are performed; and step (4), prevention and control aiming at the urban orchards are performed. The method provided by the invention provides effective theoretical and practical guidance for the agricultural non-point source pollution of a novel agricultural production mode through establishing a comprehensive prevention and control technical system for the agricultural non-point source pollution, provides scientific basis and technical demonstration, achieves good pollution removing effects, and has significant economic benefits.

Description

technical field [0001] The invention relates to a comprehensive prevention and control method, in particular to a classified comprehensive prevention and control method for urban agricultural non-point source pollution, which belongs to the field of ecological agriculture. Background technique [0002] With the increasing complexity of agricultural production models, the governance of agricultural non-point source pollution is increasingly facing more new challenges. The current theories for the prevention and control of agricultural non-point source pollution, such as the "source reduction-interception-remediation" theory, are only used to guide the practice in some typical areas, but there are no examples of agricultural non-point source pollution generated under some new agricultural development and production models. , it is necessary to conduct research and provide guidance on agricultural non-point source pollution caused by these new forms of agricultural production m...
