Problems solved by technology

[0003] However, the existing ecological network cannot fully and truly reflect the estuary area, and is not closely related to biodiversity, so it is impossible to give realistic, feasible and reasonable suggestions for biodiversity conservation
[0004] Through the above analysis, the problems and defects of the existing technology are: the existing ecological network cannot fully and truly reflect the estuary area, and at the same time, it is not closely related to biodiversity, and cannot give a real picture for biodiversity protection. Feasible and Reasonable Advice

Embodiment 1

[0091]The method of constructing river network for biodiversity protection provided in the embodiment of the present invention is asfigure 1 As shown, as preferred embodiments, such asFigure 4 As shown, the method of continuous evaluation of the build-up river network based on the collected river network is provided by the embodiment of the present invention, including:

[0092]S201, the node based on the river network divides the river into multi-segment, determines the barrier coefficient of each barrier of each section; the first distance of each river source head according to each barrier is the first distance of the river from each block. The second distance of the estuary determines the first position correction factor of each barrier;

[0093]S202, determine the second position correction factor of each barrier according to the first multi-year average natural radio amount and the estuary of the river or the second multi-year average natural radio flow of the river in the position ...

Embodiment 2

[0098]The method of constructing river network for biodiversity protection provided in the embodiment of the present invention is asfigure 1 As shown, as preferred embodiments, such asFigure 5As shown, the method of evaluating the biological diversity of rivers through the biodiversity evaluation module based on river connectivity evaluation results and collected related data, including:

[0099]S301, acquires collected river data and river connectivity evaluation results, and obtain node data of the build river network; obtains aquatic biological data at the nodes of each river network;

[0100]S302, according to the aqueous biological data, using the CHAO differential index, calculate aquatic biodiversity index, and determine aquatic biodiversity matrix;

[0101]S303, based on the determined aquatic biodiversity matrix, river connectivity evaluation results, river coastal environmental data, river feature, river type, river history change data, and related river data for biodiversity evalu...

Abstract

The invention belongs to the technical field of ecological hydrology, and discloses a river network construction method and system for biodiversity protection and application of the river network construction method and system. The river network construction system for biodiversity protection comprises an area range determination module, an area historical data acquisition module, a river segmentation module, a river coastal environment acquisition module, a river type determination module, a river data acquisition module, a central control module, a river network construction module, a river connectivity evaluation module, a biodiversity evaluation module, a suggestion generation module, a data storage module and an update display module. Edges and nodes of the river network are determined based on environment and river data, quantitative analysis is performed on the river in combination with connectivity and biodiversity, influence factors of river factors on biodiversity protection can be determined, suggestions and suggestions of biodiversity protection can be given. The invention has important significance on water resource distribution, biodiversity protection, ecological hydrological analysis and research and the like.

Description

Technical field[0001]The present invention belongs to the field of ecological water literature, and more particularly to river network construction methods for biodiversity protection and its application.Background technique[0002]At present, with the rapid development of socio-economic, the process of urbanization is constantly accelerating. Regional environments, especially in the densely populated estuary, the important issues faced in the process of urbanization high-speed advancement are regional landscape crushing and hanger area atrophy, and thereby causing spatial heterogeneity to decline the regional ecosystem continuity, The normal ecological process is blocked, and the ecological function is lowered. In the face of this class of ecological environment, it is proposed to build an ecological network. The method will make the crushed habitat spots through the way of recovering or reconstructing an ecological corridor, thereby improving and enhancing the original isolated. The...
