The Residue Dynamic of Quizalofop-P-tefuryl 4% EC in Bean Field ZHANG Hao, WANG Yan, LU Zhong-bin (College of Resource and Environment, Jilin Agricultural University, Changchun 130118, China) Abstract: In order to make up a standard procedure for safe use of quizalofop-P-tefuryl on soil and bean,a field supervised conducted to reveal dynamic of quizalofop-P-tefuryl in soil and bean,respectively.

4%糖草酯乳油在大豆植株和土壤中的残留动态张浩，王岩，逯忠斌(吉林农业大学资源与环境学院，长春 130118)摘要：为了制定糖草酯在大豆上的安全使用标准，采用田间试验方法，研究了糖草酯在大豆及土壤中的残留动态，应用HPLC测定了糖草酯在大豆及土壤中的残留量。

In order to select the reasonable method,using water drop penetration time and the Molarity of an Ethanol Droplet technique,soil water repellency in Leymus chinensis grassland in Xilinhaote region of Inner Mongolia was determined.

土壤斥水性不利于农业生产和环境的可持续性发展，如导致土壤水分的不均匀分布[2]；使水中携带的溶质更快地进入地下水[3]；降低土壤持水能力，加强地表径流和侵蚀[2]。

Based on the Changxing Agricultural Geologic Environment Survey in Zhejiang Province, the paper marks the abnormal plot of some elements in the soil of surface layer in Meishan Basin, such as Cd、Hg、As、Ni、Pb、S、Br、Cl、F, and lays emphasis on the spatial distribution of the abnormalism, and also evaluates the environmental quality of soil and shallow groundwater preliminarily. The results show that enormous coal gangue was stacked with open-air as a result of coal mining of Meishan Basin.

文章以长兴县农业地质环境调查结果为依据，结合区域浅层、深层土壤及浅层地下水测试分析数据的统计特征，圈定了煤山盆地土壤中Cd、Hg、As、Ni、Pb等重金属和与采煤有关的S、Br、Cl、F等不同元素的地球化学异常图，重点分析了异常的空间表现特征，并对土壤、浅层地下水环境质量进行初步评价。

In the agricultural activities, heavy metals from atmosphere,mineral fertilizer, pesticide, wastewater irrigation and industrial waste materialall enter the soil directly and result in the cumulation of cuprum and zincum inlarge amounts in soil.

在农业生长中，来源于大气、矿质肥料、农药、污灌以及工业废弃物的重金属直接进入土壤，造成铜、锌在土壤中大量累积，破坏了土壤环境中的营养元素平衡，降低了农产品的产量和质量，威胁着人、畜的健康。

This paper based on Precision Agriculture development of China, and focused on several key problems for developing Precision Agriculture, especially field spatial information distribution processing method. The trail farm is located in Shunyi, Beijing. The area is 11 hectors. We sampled the soil, and got soil spatial distribute data , crop growing status distribute data (such as crop population, crop height, plant dry weight), yield distribute data (such as yield per mu, ears per mu, seeds number per ear, weight of thousand grain, plant yield).

本文在探索我国精细农业发展道路的基础上，以当前开展精细农业实践急需解决的关键问题之一—农田空间分布信息处理方法研究作为切入点，通过对北京顺义&三高&农业示范区一块面积约11公顷的农田进行了定点采样试验，得到土壤空间分布信息、苗情分布信息（株数、株高、地上干物重等）、产量分布信息（亩产量、亩穗数、穗粒数、千粒重、生物产量等）。

Environmental protection and sustainable development in agriculture has become key problems of human being in nowadays,and the heavy metal contaminates is one of severe pollutive originations,which enters the human body by food chain and endangers the health of human being. In this paper,the origination of heavy metal in soil was conducted and the review about the methods of heavy metal spacial variation in soil was discussed. The proposed implications were as follow:① the study on spacial variation of the heavy metal should be conducted by Geostatistical methods combinated with 3S technic;②a model about the geostatistics and the spacial variation of heavy metal was built.

环境保护及农业可持续发展成为当今世界人类面临的重要课题，重金属污染尤为突出，并通过食物链进入人体，对人体健康构成极大危害；本文简要分析了土壤重金属的来源，并对土壤重金属特性空间变异定量研究中所涉及的主要分析方法作了初步介绍；提出了重金属特性空间变异定量研究方法的两点启示：①地统计学与3S技术的结合来研究重金属空间变异；②提出了地统计学与土壤重金属空间变异分布建模。

With the test of growing plant in pot,the enrichment characteristics of heavy metal Cu in wheat were studied.

土壤污染是农产品不安全的源头，土壤生态安全与农业可持续发展是现代土壤学的根本任务[1-2]。
