在有機農產品交易中存在著顯著的信息不對稱，對制度有著更高的要求，表現在：有機農產品的生產因為禁止使用農藥、化肥等各種化學投入品，在營養、安全、健康等方面優于普通農產品；因為其優良的品質和環境友好、社會公平等附加效用，消費者願意以比普通農產品更高的價格購買，但前提是必須保證產品的有機真實性；由於有機農業生產投入受到很大限制，生產成本增加，而產量又可能降低（尤其是在轉換期） ，生產者需要以較高的產品價格作為補償；在外觀上難以區分有機農產品與普通農產品的差異在外觀上，即使通過檢測也難以驗證有機產品的真實性。Based on data generated, we classify 8 recipients into three categories in terms of possible environmental impact : ( 1 ) low risk of gene flow to common cultivars ; ( 2 ) intermediate risk to common wild rice with same aa genome ; ( 3 ) high risk to ms lines. 2. development of a specific database for toxin and anti - nutrient proteins bioinformatics is a very useful tool for risk assessment of gm foods
從轉基因水稻的環境風險考慮，轉基因向常規稻的基因漂流頻率及最大距離都較小，相應地其風險也較低；向不育系的基因漂流頻率較高，最大漂流距離也較大，相應地其風險也較高，應重點考慮轉基因漂流對雜交稻制種純度的影響及其可能引起的環境風險後果；轉基因向普通野生稻的基因漂流頻率中等。The common map is scanned into grid map, and then vectored in mapinfo. after vectoring, vector data are matched and the spatial coordinate data of resident points, water system and other data are gained. the coordinate of reference points in the freeway are gathered by gps, then after data processing, coordinate transition, data inputting, it turn into the freeway graph, which composes the freeway electronic map with the materials subsidiary to the freeway
