Wang Xiaoqiao,Liao Guiping,Wang Fang,Li Jinwei and Qiu Chunrong

Chinese Agricultural Science Bulletin 2015, 31 (32): 253-260. DOI: 10.11924/j.issn.1000-6850.casb15040080

In order to help users to quickly retrieve agricultural information, a multidimensional classification model of agricultural information was designed according to the new characteristics of the users’ demand for agricultural information. Then the multidimensional classification model scheme based on OLAP was also put forward from the perspective of information efficient storage and processing. Finally Hunan rape network information was taken as an example to collect experiment data and classify the correlative information to realize the storage structure of agricultural information classification based on OLAP. Experimental results showed that: (1) the improved multidimensional model of agricultural information classification could more effectively express the information collected randomly from agricultural network; (2) the dimensions of industry, time, region and form were objective, and the dimensions of information attribution, industrial chain and information content were subjective; (3) empty value “null” could be used to express the value when the information was not determined or there was no data in the dimension; (4) agricultural science and technology information had no data in time and space dimension. OLAP multidimensional agricultural information classification model designed in this paper could not only view relevant data from each dimension, but also extract data from different dimensions to analyze in depth, which laid an important foundation for personalized agricultural information push service. Realization of multidimensional agricultural information storage structure was necessary for data analysis and dimension optimization in follow-up agricultural information work.

Zhang Caixia,, Yang Qinke,, Duan Jianjun

Chinese Agricultural Science Bulletin 2005, 21 (12): 411-411. DOI: 10.11924/j.issn.1000-6850.0512411

Abstract + (1851)

The regular grid digital elevation models (DEMs) with high quality are the premise of calculating slope gradient, aspect, and modeling hydrology accurately. With the input data commonly available and the known characteristics of elevation surfaces, ANUDEM utilizes an iterative finite differential interpolation technique and the drainage enforcement algorithm to remove all sink points in the output DEM that have not been identified as sinks in the input sink coverage and ensure connected drainage structure and sensible representation of ridges and streams. In addition, the output diagnostic files are useful to identify large elevation errors and locations where elevation data and streamline data and then improve the quality of the output DEM. Example of a typical catchments in the Loess Hilly and Gully area, the quality of the DEM, which was produced based on the digital map (1:10000) by ANUDEM, was evaluated in terms of the shade map of the DEM, the derived contours map, streamlines and slope form the DEM. The study shows that the surface of DEM is smooth, the contours and the streamlines form the DEM are matching well to the originals and the slope is correct, so such high quality DEM can represent the shape and drainage structure of the real landform accurately. Therefore, ANUDEM is a good method to produce DEMs with high quality.

Abstract + (1551) PDF (704232KB) (615)

Traditional plant N status diagnosis methods such as plant total N content, biomass and stem sap nitrate concentration test, which need destructive plant sampling and laboratory analysis, can not be used in regional scale due to its too time cost and labor cost. In this research, field experiment with digital image analysis method had been used in wheat N status diagnosis at shooting stage. The results showed the normalized redness of R/(R+G+B) well correlated with wheat N status parameters of SPAD chlorophyll meter readings, stem sap nitrate concentration, shoot total N content and upland biomass, and the correlation coefficients (r) with those parameters were 0-809-0.946. The normalized redness R/(R+G+B) is a good indicator of wheat N status by using digital image analysis method.

The forest resource information management is facing new opportunities and challenges in the era of big data. It is urgent to probe the architecture design and application of forest resource information service in the intelligent forestry. Based on cloud computing theory and technology, the connotation and characteristics of forestry resource information cloud service were deeply analyzed, and thus the architecture design meta-model of forestry resource information cloud service was proposed by referring to IEEE 1471 2000. Then, the overall structure and the distributed and collaborative deployment pattern of forestry resource information cloud service nodes were designed by applying the layer architecture model and the architecture meta-model. Meanwhile, the forestry resource monitoring service system was carried out in SFA (State Forestry Administration) and Liaoning Province to verify the effectiveness of FRI-CSA (cloud service architecture of forestry resource information). The results showed that the requirements of forestry resource monitoring business in big data environment were fulfilled by the FRI-CSA which had the characteristics of general applicability and replicability to some extent.

【OBJECTIVE】A novel method for measuring area of corn leaf is proposed using Image processing software developed with Visual C++6.0 based on image processing techniques and Digital Cameras. 【METHOD】Firstly, corn leaf and reference board which are hung in the vitical wall are captured by a color digital camera in the same image. Secondly, the blue component of the image are extracted, the noise are eliminated used the median filtering、dilation and erosion. the corn leaf are segregated from the background by Ostu threshold segrement method. Thirdly, every reginal of the object is labeled and calculated its’ pixel number. Lastly, the corn leaf’s real area can be got through the corn leaf’s pixel number and the image resolution ratio.【RESULT】The result shows that there are close relationships between digital image processing method and “Maximum length ×width”ruler method, and digital image is more accurate than the “Maximum length ×width”ruler method. 【CONCLUTION】This kind of shooting method can avoid engendering the geometric distortion. the intensity of the object and the background has the most different in the blue component of the image.
