Description
Technical field
The invention belongs to Ecosystem Technologies fields more particularly to a kind of utilization soil animal to assess Karst ecosystem
The method of revegetation potentiality.
Background technology
Karst ecosystem is a kind of ecosystem of fragility, and because of mankind's unreasonable development, large area is degenerated,
Seriously threaten agriculture production environment or even human survival.The revegetation potentiality of degeneration Karst ecosystem is assessed to carrying out karst
The recovery of the ecosystem and reconstruction are significant.Existing evaluation measures are based primarily upon the recovery situation of aboveground vegetation, but
Since plant growing cycle is long, and related work can only be carried out in situ in the wild, thus time-consuming, and manpower, financial resources input are big.Soil
Earth animal is the important component of bio-diversity, and species quantity is more, density is big, distribution is wide, short (the exhausted big portion of life cycle
Divide species about 30 days), it is numerous convenient for indoor culture and expansion, thus be the effective object for assessing ecosystem restoration potentiality.
In conclusion problem of the existing technology is:Plant gives birth in the means of existing assessment Karst ecosystem
Long period is long, and time-consuming for assessment;Under the conditions of regional environment, soil animal is most suitable for the acquisition of living condition.
Invention content
In view of the problems of the existing technology, the present invention provides a kind of Karst ecosystem is assessed using soil animal
The method of revegetation potentiality.
The invention is realized in this way a method of Karst ecosystem revegetation potentiality being assessed using soil animal,
The method is using soil animal as object;By cultivating examination in field original position earth pillar Transplanting Test and soil animal resting egg library room
It tests, the diffusion revegetation potentiality and resting egg library revegetation potentiality of overall merit karst soil animal are various from terrestrial life
Property angle, the recovery to give birth to fragile state system for karst provides foundation with integrated control.
Further, the method for assessing Karst ecosystem revegetation potentiality using soil animal includes the following steps:
Soil animal spreads the assay method of revegetation potentiality:With choosing the sample of 4 kinds of different Rock Desertification Degrees;In each sample
The pedotheque on 10 centimetres of surface layer is acquired, 1 part of removal soil fauna, 1 part is control;By 20 mesh holes of each pedotheque
The mesh bag of diameter installs, and makes a diameter of 13 centimetres of earth pillar, samples original place with being put back into corresponding sample respectively, is repeated 7 times in sample prescription;
The 15th day after transplanting, 30 days and 60 days sample respectively, the soil animal sample that separation, identification obtain;It is carried out at the same time soil
The measurement of physicochemical property;
The assay method of soil animal resting egg library revegetation potentiality:To the without stony desertification sample native of removal soil animal live body
20 DEG C, 23 DEG C, 25 DEG C, 27 DEG C and 30 DEG C and 20%, 25% and 30% soil moisture is respectively set in earth sample, carries out indoor
The optimal culture condition of soil animal suspend mode egg hatching is explored in culture;The topsoil on 4 kinds of sample ground is gone through cold shock method at adult
After reason, under the optimum temperature and damp condition filtered out, sampled after culture being protected from light in incubator 30 days;Separation, identification obtain
Soil animal sample;Each processing is repeated 12 times.
Further, the sample for choosing 4 kinds of different Rock Desertification Degrees for no stony desertification R0, potential stony desertification R1, slightly
Stony desertification R2 and moderate stony desertification R3.
Further, the original place that samples with being put back into corresponding sample respectively will remove fauna and control without stony desertification sample
Ground soil in-situ with being transplanted to no stony desertification sample, is denoted as OR0 and WR0 and OR1, WR1, OR2, WR2, OR3 and WR3 is 8 kinds total
Processing.
Advantages of the present invention and good effect are:Guizhou is the area that China's karst landform is most developed, and belongs to typical
Ecologically fragile areas.This area's bio-diversity has extremely important in maintaining and improving ecosystem stability and its ecological functions
Value.The present invention investigates and analyses soil animal diffusion under Karst Area of Guizhou difference Rock Desertification Degree and restores by taking Puding County as an example
Potentiality verify soil animal resting egg library revegetation potentiality under Karst Rocky Desertification background.To for Karst Rocky Desertification Region it is crisp
The recovery of the weak ecosystem provides scientific basis with integrated control.It can be completed, can be improved existing in entire two months test periods
There is 50% or more evaluation measures efficiency.
