Yield distribution in space of the crop in the specific region.
Below with the previously selected biological crop (i.e. energy crop) for cassava, the corresponding biological liquid fuel generated is
For alcohol fuel, exemplary illustration builds the yield space of the GEPIC model analog analysing cassavas of the cassava in specific region
The process of distribution.
Specific simulation process can be divided into data prediction, model localization process, model verification and modeling etc.
Step.
(1) data prediction
One of the difficult point that the GEPIC models of cassava in structure specific region are simulated is the preparation stage of data.
GEPIC models are more stringent to the call format of input data, especially soil data and meteorological data.Per the category of one kind soil
Property is stored in a specified pattern in text file (txt), including soil effective soil layer thickness, hydrogen ionexponent
(PH), the dozens ofs attribute such as organic carbon content；The moon meteorological data of the long-term sequence of each grid includes precipitation, highest
Temperature, lowest temperature and precipitation number of days, these data are also stored in txt in a specified pattern.Since data volume is larger, may be used
C# language programming handles data.
(2) model localization process
Since there is the parameter of GEPIC models significant regionality, the plant growth parameter built in model to be defaulted as mainly
Reference value from Oregonian American national laboratory.These plant growth parameters for example can be the harvesting of biological crop
Index, the environment highest temperature and lowest temperature etc..When GEPIC models are applied to the specific region, it is necessary to according to the specific region
Field survey data or data in literature are mutually to be fitted with the specific region to plant growth parameter processing built-in in GEPIC models
The plant growth parameter answered, to obtain the growth parameter(s) of the cassava in the specific region.
(3) model is verified
It after being localized processing to GEPIC models, needs to verify model accuracy, to determine the reliable of model
Property.Such as it can be by the way that the precision of analog result and measured data be carried out contrast verification.In one embodiment, Guangxi is utilized
Cassava plantation measured data to row verify.Guangxi is Chinese Cassava big producing province, accounts for the whole nation harvest gross area and fresh sweet potato total yield
The 60% of amount, planting technology is more mature, and statistical data is more perfect.Based on this, Zhuang nationality in Guangxi autonomy in 2010 can be built
The cassava GEPIC models in area, and the statistical result pair of the actual spatial distribution using the cassava of Guangxi Zhuang Autonomous Region in 2010
The simulation precision of model is verified.
(4) modeling
By (three) model verify, after the precision of model reaches preset requirement, it is believed that localization process it
GEPIC models afterwards are reliable.Hereafter, can by (one) in the data handled well be input to the specific region of structure
In the GEPIC models of interior cassava, simulation obtains the Yield distribution in space of the cassava in the specific region.
In accordance with an embodiment of the present disclosure, by data above pretreatment, the verification of model localization process, model and pattern die
Intend and etc., sky of the cassava in the specific region can be obtained based on biogeochemical model GEPIC modelings
Between output distribotion, the space output distribotion is associated with the spatial distribution of geographic factor in the specific region.Further to divide
It analyses the space output distribotion of cassava alcohol fuel and assesses the geographical spatial difference of the energy-saving and emission-reduction benefit of cassava alcohol fuel
It provides the foundation.
