The radical reason of lower ecosystem productivity and disharmonic developing in this ecotone is the improper configuration inner animal husbandry for example of ansai county and big animal scale exceeding the threshold of the primary productivity for example of wuchuan county, which above - mentioned leads to the fact that coupling mechanism between agriculture and animal husbandry system has not been established, and agriculture and animal husbandry is still in the state of disharmonic on the whole. 3
主要表現為兩種典型結構模式,一種以安塞縣為代表,農牧能值總體利用率較高,但畜牧業內部結構偏重食糧動物使得高質能轉化率低下;另一種以武川縣為代表,農牧業結構總體上朝趨于協調方向發展,但畜牧業規模過大,由於草畜平衡嚴重失調,導致農牧系統耦合機制難以穩定。Animal growth hormone ( gh ) is a very important protein hormone which is secreted by the anterior pituitary cells and plays many important roles on animals, such as regulating somatic growth and stimulating appetite, affecting various metabolic activities and improving the food transformation rate, etc. although gh has so many functions, it is limited in the application and functional researches because the natural growth hormone content is very low and difficult to purify
動物生長激素( growthhormone , gh )是由腦垂體間葉細胞分泌的一種多肽激素,具有調節生長發育,參與體內代謝調節,增進食慾,提高食物轉化率等作用,然而垂體中生長激素含量極低,分離純化比較困難,使得生長激素生理功能的進一步研究和應用受到限制。They are agricultural productive materials price growth rate, sown area of grain crops growth rate, grain yield per area growth rate -, natural disaster covered grain areas growth rate, net grain import change rate, grain reserve change rate, population growth rate, per income growth rate, city and town population growth rate, food industry production value growth rate, year - end pig number growth rate, medical & pharmaceutical and textile industry production value growth rate, grain marketization degree, inflation rate using the previous year as base year ( preceding year = 100 ), public grain purchases price growth rate, investment in agricultural science and technology growth rate, investment in agricultural infrastructure growth rate, growth rate of graduates number from agriculture, forestry, science & technology universities and colleges and specialized secondary schools, government expenditure for agriculture and agricultural credit growth rate, international grain price growth rate, rmb exchange rate growth rate, last grain price growth rate, economic crop price growth rate, meanwhile, a new method is attempted to be used in this paper and the grain price early - warning problem is transformed into machine learning problem by introducing statistic learning theory and svm method which are gaining popularity in machine learning field at present in the world
在此基礎上,篩選出23個警兆指標:農用生產資料價格增長率、糧食播種面積增長率、糧食單產增長率、糧食受災面積增長率、糧食凈進口量變化率、糧食儲備變動率、人口增長率、人均收入增長率、城鎮人口增長率、食品工業產值增長率、豬年末頭數增長率、醫藥紡織工業產值增長率、糧食市場化程度、以上年為基年的通貨膨脹率、國家糧食定購價格增長率、農業科技投入增長率、農業基礎設施投入增長率、農、林、科技高校大、中專畢業生人數增長率、財政支農資金比重及農業信貸增長率、國際糧食市場價格增長率、人民幣匯率增長率、上期糧食價格增長率、經濟作物價格增長率。同時論文在預警方法上作了新的嘗試,把糧食價格預警問題轉換成一個機器學習問題,引進當前國際上機器學習領域中比較熱門的統計學習理論和支持向量機方法,用順序回歸演算法對歷史數據進行學習建立了糧食價格預警模型。
