Abstract

The invention provides a method for monitoring earth surface drinking water source water gathering area ecology, and relates to the field of specific area ecological environment quality monitoring. The method aims to solve the problem that ecological environment quality assessment uncertainties exist due to the fact that an existing earth surface drinking water source water gathering area ecology monitoring method neglects non-uniformity, systematicness and precision of an underlying surface. According to the method, remote sensing information inversion is combined with a field survey to build a water source water gathering area ecology monitoring index model with an administration unit, a water gathering unit and a small watershed as a monitor unit, a comprehensive monitoring result F(Ri) is obtained according to the formula F(Ri)=w1R1*w2R2*w3R3, wherein i is equal to 1 or 2 or 3, R1 is the risk degree of a risk source, R2 is the fragility of an ecological system and R3 is the loss degree of the ecological system. The method has the advantages that a monitoring target is clear, an index system is complete, the model is simple and practical and the dynamic property and precision are high.

Description

technical field [0001] The invention relates to the field of ecological monitoring, in particular to an ecological monitoring method for surface drinking water source catchment areas. Background technique [0002] The underlying surface refers to the earth's surface, including oceans, land, plateaus, mountains, plains, forests, grasslands, and cities on land. Parameters such as temperature, moisture, and surface shape of each part of the underlying surface are quite different, so the underlying surface has non-uniformity. [0003] The existing regional ecological monitoring methods are mainly designed for cities, river basins, etc., and lack index systems and related index models for ecological monitoring methods for surface drinking water source catchment areas; for watershed monitoring methods, due to the lack of multi-temporal quantitative Supported by spatial data, it is difficult to ascertain the complexity of the process of the underlying surface in complex watersheds...
