In order to better understand a kind of Valuation Method based on grassland resources quality provided by the embodiments of the present application, under
Face first corresponds to briefly be introduced with the application environment of the Valuation Method based on grassland resources quality.The embodiment of the present application
A kind of grassland resources asset level evaluation criterion is provided, specific as follows:
Optionally, to meadow carry out " etc. " evaluation, " grade " evaluation and " grade " evaluate, determine vegetable plot by three kinds of evaluations
Resource assets grade.
Optionally, meadow is carried out " etc. " in terms of evaluation, be specifically as follows: meadow " etc. " be according to all kinds of in careless group
Nutritive value, palatability and the grazing rate of herbage are that index is evaluated.Descriptive qualitative side is used from reality at present
Method, first by field site observation, to there are the herdsman masses for practicing knowhow to access and various regions many years scientific research at
Fruit carries out overall merit to various forage plants.Mark off it is excellent, good, in, low, bad five class；It then is that evaluation is basic with Grassland Type
Unit, further according to the weight percent shared in careless group of five class quality herbages in type be divided into it is excellent, good, in, it is low, five bad
Equal meadows.
Wherein, the evaluation of forage plant is as follows:
Excellent herbage: various domestic animals are preferred particular about food from careless group；Gross protein value > 10%, crude fiber content <
30%；Herbaceous stem is soft, and resistance to herding property is good, and cold season storage rate is high.
Good equal herbages: various domestic animals are fond of, but not particular about food；Gross protein value > 8%, crude fiber content < 35%；It is resistance to
Herding property is good, and cold season storage rate is high.
Medium herbage: various domestic animals search for food, but degree of searching for food, not as good as excellent class and good class herbage, withered and yellow rear herbaceous stem becomes rapidly
Thick and stiff or Green stage has peculiar smell, and domestic animal is reluctant to search for food；Gross protein value < 10%, crude fiber content > 30%；Resistance to herding property is good
It is good.
Low herbage: most of domestic animals are reluctant to search for food, and only the camel or goat of resistance to crude feed are fond of, or good forage in careless group
It just searches for food after having been searched for food；Gross protein value < 8%, crude fiber content > 35%；Resistance to herding property is poor, cold season storage rate
It is low.
Of inferior quality herbage: domestic animal is unwilling to search for food or seldom search for food, or only in starvation, just there are slight poison in feeding or certain season
Evil effect, only searches for food in certain season on a small quantity；Resistance to herding property is poor, nutrition content low herbage no significant difference in.
Optionally, it is a kind of it is possible " etc. " criteria for classifying is as follows:
According to the above five classes quality herbage, Grassland Quality is divided into five etc. by weight percent shared in careless group.Respectively
" etc. " the meadow criteria for classifying is shown in Table 1, it is specific as follows:
1 meadow of table " etc. " the criteria for classifying
| Meadow " etc. " | The criteria for classifying |
| I equal (excellent) meadow | Excellent herbage accounts for 60% or more |
| II equal (good etc.) meadow | The above herbage such as good accounts for 60% or more |
| III equal (medium) meadow | The medium above herbage accounts for 60% or more |
| IV equal (low) meadow | The low above herbage accounts for 60% or more |
| V equal (of inferior quality) meadow | It is of inferior quality and edible forage does not account for 40% or more |
Optionally, in terms of carrying out " grade " evaluation to meadow, it is specifically as follows:
It is index with meadow grass group's yield, the nature of meadow grass group is represented with the measured value in grassland yield highest month in year
Productivity level, and national meadow is divided into 8 grades by green forage yield.When working out national hundred a ten thousandth Rangeland Resources Map,
Regulation presses every annual output hay partition level, and each grade standard such as table 2 is specific as follows:
The criteria for classifying on 2 meadow of table " grade "
Optionally, in terms of carrying out " grade " evaluation to meadow, it is specifically as follows:
On the basis of to grassland resources etc. and grade evaluation, further progress rank of grassland overall merit could synthetically
Disclose the superiority and inferiority of Grassland Quality and the height of reflection Productivity.Such as first-class 1 grade of meadow, most for best in quality, yield
High meadow；Five equal 8 grades of meadows, for the meadow that quality is most bad, yield is minimum.
Grade evaluation standard be exactly that meadow five is equal and 8 grades of matching is sewed and, full evaluation of programme share 40 it is different
Grassland Quality is combined with yield, as described in Table 3, specific as follows.
The composite structure of 3 rank of grassland of table
By the above method, " grade " evaluation is carried out to meadow, can quickly determine the Grassland Quality on target meadow,
Efficiency when Grassland Quality determines is improved to a certain extent.
Referring to Fig. 1, Fig. 1 provides a kind of Valuation Method based on grassland resources quality for the embodiment of the present application
Flow diagram.As shown in Figure 1, the Valuation Method based on grassland resources quality includes step 101-106, it is specific as follows:
101, the yield of the edible forage on target meadow is obtained, and obtains what forage plant grew on the target meadow
Target proportion in all plants.
It optionally, can be to grass when obtaining target proportion of the forage plant in all plants that target meadow is grown
Ground is investigated, to obtain target proportion.For example, can be sampled to meadow, then calculate feeding in the sample of sampling
The ratio of plant, using the ratio as target proportion.
102, according to the yield of the edible forage, the service rating on the target meadow is determined, and according to described
