Problems solved by technology

[0003] At present, most studies on land use and non-point source pollution mainly discuss the relationship between types, quantities, patterns, etc. method, and these two methods are difficult to combine with the actual situation of the study area, and their reference value is somewhat lacking
In addition, the current research status still has the following problems: the optimization of land use structure mainly focuses on the realization of regional land economic benefits, social benefits and ecological benefits. Far away from the actual needs of the regional environment, it is not convenient to fundamentally improve the quality of the ecological environment in the region

specific Embodiment

[0043] Miyun Reservoir is currently the only source of surface drinking water in Beijing, which has important strategic significance. In this example, the method is applied to the comprehensive planning and management of the Miyun Reservoir watershed in view of the obvious decrease in the annual runoff of the Miyun Reservoir, the deterioration of the water quality, and the intensification of nutrient levels. The results of the method implementation show that:

[0044] (1) The overland flow formed at each sampling point was collected through 7 precipitation events (6 / 11, 7 / 06, 7 / 21, 8 / 25, 8 / 27, 9 / 03 and 9 / 22), and the TN, TP content. Generally speaking, nitrogen pollution is far more serious than phosphorus pollution. After precipitation occurs, factors such as rain erosion and steep slopes will increase the pollution content of runoff species on the slope. The content of TN in the overland flow formed by pine and chestnut is relatively high, and for the content of TP, all th...

Abstract

The invention relates to the technical field of river basin water environment protection and river basin comprehensive planning and management and discloses an ecological water saving and pollution control integrated land utilization optimizing method. Aiming at characteristics and defects of researches in the field of land utilization structural optimization at present, the optimizing method avoids defects in the field of land resource structural allocation research, economic benefits and ecological benefits are selected as main optimizing targets according to realistic conditions of research areas, a multi-objective linear programming model and an improved CLUE-S model are combined in terms of model selection to form a model system for planning quantity structures and spatial arrangement of various land use types, and a goal of land resource allocation optimization of the research area is achieved.

Description

technical field [0001] The invention relates to the technical field of river basin water environment protection and comprehensive planning and management of river basins, in particular to a land utilization optimization method that takes ecological water saving and pollution control into account. Background technique [0002] The increasingly serious water resource problem has seriously affected the ecological environment and social and economic development. Exploring the relationship between land use and non-point source pollution has important practical significance for improving the quality of water environment in the watershed and guiding the optimal allocation of land use in the watershed. [0003] At present, most studies on land use and non-point source pollution mainly discuss the relationship between types, quantities, patterns, etc. However, these two methods are difficult to combine with the actual situation of the study area, and their reference value is somewha...
