Research on the spatial distribution characteristics of arable land economic quality composite grade and ecology environment in Yunnan Province, China 52
ZHANG,Gengjie; ZHANG,Chuan; Liu,Shuxia; Zheng,Honggang.
ABSTRACT Understanding the distribution characteristics of arable land in Yunnan Province is of significant importance to make scientific decisionsto use and improve the quality of arable land. In this study, the distribution characteristics of the arable land grade including 129 counties were analyzed based on the accomplishment of cultivated land classification in Yunnan Province. The results showed that the average economic quality composite grade was 2.9, in a range of 1 to 13, which means that the economic quality of arable landof Yunnan Province is relatively lower. In excellent zone, the grade ranges from 1 to 10, and the average grade is 2.4. In good zone, it ranges from 1~13, and the average grade is 3.1. In medium zone, it ranges from 1~12, and...

Distribution of copper in soil and rice system of Hainan Island, China 52
Dengfeng,WANG; Haijie,HUANG; Huande,FENG; Hua,WANG; Miaojie,HAN; Zhiping,QI.
ABSTRACT This research aimed to discover the distribution and the primary influence factors of Cu in the soil-rice systems of tropical farmland. Soil samples of farmland and rice plant (stalk and polished rice) from the western region of Hainan Island were collected and studied. The results showed that the average Cu content in the topsoil of the study area was 15.75 mg kg-1; the highest Cu content (45.92 mg kg-1) was found in the rice fields of the northern area, where pyroclastic parent material is distributed. Thus, there is a potential for Cu contamination of the rice grown in this region. The average contents of Cu in the rice stalks and polished rice were 16.9 and 5.68 mg kg-1, respectively, indicating that the stalks had a larger capacity for Cu...

A FÖLDPIAC SAJÁTOSSÁGAI MAGYARORSZÁGON AZ UNIÓS CSATLAKOZÁS IDEJÉN 31
Hamza, Eszter; Misko, Krisztina.
A felmérés tapasztalatai azt mutatják, hogy a magyarországi földpiacon1 ki-várás tapasztalható. Kereslet elsősorban az egyes megyék kiváló és jó minőségű, kedvező fekvésű területei, illetve a nagyobb kiterjedésű, egybefüggő szántók és erdők iránt van. A gyengébb minőségű, kedvezőtlen fekvésű, nehezen megköze-líthető területeken, a zsáktelepülések és az elöregedő falvak környékén túlkínálat jellemző. Nehezen értékesíthetők a beékelődő, szórtan elhelyezkedő, kis méretű, illetve a rendezetlen tulajdonviszonyú (osztatlan közös tulajdonú) területek. Az eladók között nagy számban találhatók megélhetési gondokkal küzdő idősebb, il-letve öröklés, vagy kárpótlás útján földhöz jutott, gazdálkodni nem kívánó tulaj-donosok. A földvásárlók között egyre több tőkeerős...

Driving Factors and Model of Change in Arable Land Area in China 31
Lei, Zhanbo; Du, Haowen.
We analyze the characteristics of the change in arable land area in China according to the change data of arable land area and other relevant data from the year 1996 to 2006, and adopt Factor Analysis Method and Stepwise Regression Method to carry out quantitative analysis on the driving factors of arable land change of China. We also establish the regression model of driving factors and arable land area. Finally, some corresponding suggestions are put forward.
