To begin with , the status of the evaluation of vegetable plot quality in the gradation and classification and appraisement of arable land and the status of markets in the evaluation of the comprehensive quality of vegetable plot were discussed in the thesis 文章分析论述了菜地质量评价在农用地分等定级与估价中的地位以及集贸市场在菜地综合质量评价中的地位。
And how to rank the market applying delphi approach and how to ascertain the market factors " weight and marks were presented in the following parts . the author showed the process and methods of establishing the influence range model and influence degree decay model 在此基础上确定了建立集贸市场对菜地综合质量影响范围模型、集贸市场对菜地综合质量影响程度随距离变化的模型方法及模型的空间表示方法。
Jose mourinho has hit back at suggestions that chelsea are playing dirty tricks with their pitch after barcelona players claimed the blues would prefer a messy playing surface to give them the edge in wednesday ' s champions league showdown at stamford bridge 何塞?穆里尼奥在巴萨的众多球员攻击说蓝军在周三的斯坦福桥球场用一块菜地来迎接巴萨后回击了这些关于切尔西在将要迎来的对巴萨的比赛采取阴招的说法。
( 2 ) experiment analysis of swr soil moisture sensor because of cropland information excessive , ca n ' t experiment everyone , penman process soil containing water or moisture data experiment to vegetable terras cropland and gravel , prevailed experiment data , and draw experiment curve drawing of differ soil ( 2 ) swr型土壤水分传感器的试验分析由于农田信息繁多，不能一一研究，故笔者只对菜地、田间、砾石地分别进行了土壤含水量试验，获取了试验数据，并绘出了不同土质的试验曲线图。
The vegetable plot quality was selected as the research object from many contents which were in great need of studying , and the calculation method and law was probed which reflected the influence of markets on the quality of vegetable plot in order to provide the reference to the classification and appraisement of vegetable plot 本文从众多急需研究的内容中切其一隅，以菜地质量为研究对象，从集贸市场对菜地质量的影响入手，探索测算方法和规律，为更科学地处理菜地级别和价格提供参考。
The third class markets had nine , for example nanqiema market and nangao market and etc . the markets of the fourth class included 13 markets . based on it , the chain functions between market area and annual total turnover , annual total turnover and annual agricultural byproducts turnover , annual agricultural byproducts turnover and the influence distance of markets were put forward 建立了栾城县集贸市场面积、年总成交额、年农副产品成交额与菜地质量影响范围之间的互算函数关系，通过市场面积、年总成交额、年农副产品成交额三者之一便可确定集贸市场影响范围，从而提高了函数模型的可操作性。
By the ranking model by similarity to ideal point based on m and n , the criterion of cultivated land can ’ t be used as plant cash crops and the criterion of cultivated land should priority used as plant cash crops and the criterion of cultivated land can ’ t be used as construction land and the criterion of cultivated land should priority used as construction land were confirmed . finally , the evaluation of cultivated land grade , realistic class , and potential class were all demonstrated and the result of cultivated land grade , realistic class , and potential class were all verified in a case study in changsha county changsha city , hunan province . by calculated cultivated land coefficient m and n and confirmed c _ m and c _ n of the ranking model by similarity to ideal point , the result 0 . 5032 < c _ m 0 . 9931 was confirmed as the criterion of cultivated land should priority used as plant 最后以湖南省长沙县作为典型研究区域,实证了耕地等、现实级和潜在级的评价,并分析了其评价结果的可靠性;通过计算耕地经粮系数和建粮系数,及逼近于“理想点”的排序模型中的c _ m和c _ n确定了长沙县0 . 5032 < c _ m 0 . 9931为耕地应优先用作菜地等经济作物用途和0 . 0126 c _ m < 0 . 5037为耕地不应用作菜地等经济作物用途的判别标准;确定了长沙县0 . 5035 < c _ n 0 . 9937为耕地应优先用作建设用地用途和0 . 0139 c _ n < 0 . 5035为耕地不应用作建设用地用途的判别标准;最后阐明了c _ m 、 c _ n在种植业结构调整、耕地保护和土地管理中的应用价值。
Soil borne disease is a great headache to the vegetable growers in pengzhou city , sichuan province . in order to help our local partners to address this problem , a symposium on vegetable soil borne disease prevention and control was conducted at pengzhou agriculture and animal husbandry bureau on september 1 , 2005 . the event was co - sponsored by the vegetable department of chengdu municipal agricultural committee , chengdu new vegetable farmland foundation office and 蔬菜土传病害是彭州蔬菜生产上的严重问题，为帮助当地合作伙伴解决这一难题，蔬菜土传病害防治研讨会于2005年9月1日在彭州市农牧局成功举行，这次研讨会由成都市农委蔬菜处成都市新菜地基金管理办公室
The model of first class market was y = - 0 . 2612x3 + 5 . 518x2 - 38 . 473x + 129 . 05 ( r2 = 0 . 812 ) . the model of first class market disclosed the phenomenon of three obvious influence phases . at the range of 0 - 5 km around the first class market , the influence of market on the vegetable plot quality changed faster , and the range belonged to a zone of high investment - output in vegetable planting 一级市场模型为y = - 0 . 2612x ~ 3 + 5 . 518x ~ 2 - 38 . 473x + 129 . 05 ( r ~ 2 = 0 . 812 ) ，该模型揭示了一级集贸市场对菜地质量的影响随距离变化表现出明显的三段性，即一级市场周围0 5公里范围内为影响变化较快，属于蔬菜种植高投入高产出区； 5 9公里范围内影响变化平稳，属于蔬菜种植投入产出过渡区； 9 14公里范围内影响变化再次变快，属于蔬菜种植低投入产出区。
( 5 ) the organic matter , total nitrogen , available phosphorus content were different between different land use types in 1980 and 1999 , the order of these nutrients content in different land use types was irrigated land > rained farmland > grassland in 1980 ; the order of these nutrients content in different land use types in 1999 was vegetable land > irrigated land > rained farmland ; the changes of organic matter , total nitrogen , available phosphorus content were different between different land use types from 1980 to 1999 , the order of these nutrients content change was vegetable land > irrigated land > rained farmland > grassland ( 5 ) 1980年，土壤有机质、全氮、速效磷三种养分含量在旱地、水浇地、荒草地三种用地类型间的变化规律是水浇地旱地荒草地，而速效钾含量在三种用地类型之间的变化规律为旱地水浇地荒草地。 1999年，土壤有机质、全氮、速效磷含量在不同用地类型之间的变化顺序为菜地水浇地旱地；而速效钾含量的变化顺序却为旱地菜地水浇地。
