Problems solved by technology

[0005] The invention provides a method for testing the connectivity between species by means of mathematics to solve the problem of ecological fragility in the alpine region of the northwestern Yunnan plateau, where alien species are not suitable for the local ecological environment, and it is extremely difficult to realize the ecological restoration of the construction road section by using the existing method, and winter The management measures are complicated, the cost of management is high, and it is difficult to survive

Embodiment

[0027] This embodiment provides a method for monitoring and evaluating the ecological restoration of vegetation on the railway green passage in the alpine plateau of Northwest Yunnan. The specific method is as follows:

[0028] 1) Seed germination rate and seed activity test of restored species

[0029] Select a fixed number of seeds for the restored species purchased and collected, use a seedling tray and a weed-free substrate, observe and record the germination rate and survival rate after sowing;

[0030] 2) Site survey of community plots

[0031] In each recovery test section, set 5*5 or 5*3 (due to topographical limitations) sample squares according to different slope directions, slope positions, slopes, soil bedrock matrix, and moisture conditions. Set the four corners of the sample squares. Fill in the monitoring record form, identify inaccurate plants in the wild, and collect specimens for accurate identification;

[0032] Monitoring period: The first monitoring is carried out ...

Abstract

The invention provides a method for carrying out inter-species associativity test by utilizing a mathematical mode. Correlation test analysis of pairwise combination between species is carried out; inthe future, green channel protection plants of related engineering are configured and matched; the. A principle and the method can be followed; according to environmental factors such as actual siteconditions of the a recovery area; , species with high relevance are selected to implement reasonable and scientific matching, so that the method tends to natural plant community selection artificially in railway green channel protection, blind and unscientific plant allocation in the past is avoided, the plant survival rate is increased, rapid ecological restoration of a construction road sectionis realized, and the management and cultivation cost is reduced. The invention belongs to the field of high-altitude area construction section ecological restoration.

Description

Technical field [0001] The invention relates to a method for carrying out the connection test between species using a mathematical method, and belongs to the field of ecological restoration of construction road sections in high altitude areas. Background technique [0002] According to statistics, there are not many railway projects above 3000m above sea level in our country. The Qinghai-Tibet Railway and Lanxin Railway have been built. Areas with an altitude of more than 3000m are areas for tourism development, water conservancy and hydropower development, as well as areas with backward infrastructure and fragile ecological environment. With the further acceleration of the western development, infrastructure construction in high-altitude areas will enter a new climax. [0003] In the process of infrastructure construction, it will inevitably cause damage to the fragile ecological environment. How to protect and restore the high-altitude ecological vegetation environment has alway...
