Although there are appropriate stipulations for the chattel guarantees in the law of China, this guarantee system could not adapt to the request of economy's development because of the following reasons: the scope of chattel guarantees is narrow according to relevant stipulations; the transaction cost of the chattel is high; mortgage registration of chattel is in a mess; lack of efficiently executive guarantee system, etc. To counter the problems existing in the present Chinese chattel guarantee system, in this article, the author proposed some corresponding suggestions and countermeasures, hoping to perfect the chattel guarantee system in China.

Demonstration of malaria situation analysis,stratification and planning in Minab District,southern Iran

Objective:To demonstrate malaria situation analysis,stratification and planning for an endemic area in southern Iran.Methods:Data on health system,population,meteorological parameters, malaria cases,anopheline vectors,and control activities during 2005-2007 was obtained from Minab Health Center,Minab Meteorological Station and published documents about malaria elements in the study area.A datasheet was created in excel 2003 for analysis.Results:There were 644 health staff working in Minab District including 99 health staff in malaria control program.The health facilities are distributed as follow:1 hospital with 96 beds,23 health centers including private centers(10 in Minab city and 13 in rural area of Minab District) and 119 health houses in rural areas of Minab District.Anopheles stephensi was the dominant species in Minab District,however,Anopheles dthali,Anopheles superpictus,Anopheles fluviatilis,Anopheles multicolor,Anopheles pulcherrimus and Anopheles turkhudi can also be found in the area. Anopheles stephensi was reported susceptible to malathion,propoxur,primphos-methyl,lambdacyhalothrin permethrin and deltamethrin,and resistant to DDT and dieldrin in the area.During the study period a total of 10 665 positive cases were reported,mainly due to local transmission (99.6%).Plasmodium vivax was the main causative agent followed by Plasmodium falciparum. There were reports about drug resistance of Plasmodium falciparum in the area.Conclusions: Using different parameters,Minab was classified into 3 strata.A plan was designed based on described goal,objectives and targets.The approaches of this plan were categorized into:health education,early detection and correct treatment,and vector control.Main constraints of these approaches are population movement between Iran,Pakistan and Afghanistan;vector control challenges at district,inadequate skilled medical staff in malaria case management and weak inter-sectorial coordination for malaria control,especially in urban areas.

The Major Ore Clusters of Super-Large Iron Deposits in the World, Present Situation of Iron Resources in China, and Prospect

The metamorphosed sedimentary type of iron deposits（BIF） is the most important type of iron deposits in the world, and super-large iron ore clusters of this type include the Quadrilatero Ferrifero district and Carajas in Brazil, Hamersley in Australia, Kursk in Russia, Central Province of India and Anshan-Benxi in China. Subordinated types of iron deposits are magmatic, volcanic-hosted and sedimentary ones. This paper briefly introduces the geological characteristics of major super-large iron ore clusters in the world. The proven reserves of iron ores in China are relatively abundant, but they are mainly low-grade ores. Moreover, a considerate part of iron ores are difficult to utilize for their difficult ore dressing, deep burial or other reasons. Iron ore deposits are relatively concentrated in 11 metallogenic provinces（belts）, such as the Anshan-Benxi, eastern Hebei, Xichang-Central Yunnan Province and middle-lower reaches of Yangtze River. The main minerogenetic epoches vary widely from the Archean to Quaternary, and are mainly the Late Archean to Middle Proterozoic, Variscan, and Yanshanian periods. The main 7 genetic types of iron deposits in China are metamorphosed sedimentary type（BIF）, magmatic type, volcanic-hosted type, skarn type, hydrothermal type, sedimentary type and weathered leaching type. The iron-rich ores occur predominantly in the skarn and marine volcanic-hosted iron deposits, locally in the metamorphosed sedimentary type（BIF） as hydrothermal reformation products. The theory of minerogenetic series of mineral deposits and minerogenic models has applied in investigation and prospecting of iron ore deposits. A combination of deep analyses of aeromagnetic anomalies and geomagnetic anomalies, with gravity anomalies are an effective method to seeking large and deep-buried iron deposits. China has a relatively great oresearching potential of iron ores, especially for metamorphosed sedimentary, skarn, and marine volcanic-hosted iron deposits. For the lower guarantee degree of iron and steel industry, China should give a trading and open the foreign mining markets.

Monitoring and Evaluation of Present Situation of Environmental Quality in the Sea Area near the Aojiang Estuary in Wenzou

Based on the monitoring results of environmental quality in the sea area near the Aojiang estuary in Wenzou during 2010-2012,the present situation of environmental quality in the sea area was analyzed and evaluated. The results show that p H,DO,CODMn,petroleum,and heavy metals( Cu,Pb,Zn,Cd,Hg,As and Cr) in the sea area near the Aojiang estuary did not exceed the second-class standard of Seawater Quality Standard( GB 3097-1997),but both inorganic nitrogen and reactive phosphate in the sea area exceeded the second-class standard seriously,and the water quality of the sea area was in an eutrophic state; domestic sewage and fertilizer loss were the main sources of nitrogen and phosphorus. The standard index of most evaluation factors of sediment quality except for Zn was smaller than 1,meeting the demands of sediment quality for environmental protection.

THE PRESENT SITUATION,TYPES ANDCHANGES OF CHINA'S ENVIRONMENT

Based on development level of regional societye and economy, the paper attempts oto analyze the present situation, types and change of regional environment in China through the definition of four conceptions environmental pollution index (EPI), social and economic comprehensive index (SECI), -environmental comprehensive index (ECI) and social, economic and environmental environmental index (SEECI) and some mathematical calculation, and draws someconclusions to be worth referring: 1). There exists close relation between economic development and environmental situation. With high-speed development of economy, the discharge of the three wastes in China has been increasing, but itsenvironmental social and economic benefit has also been improved the same the time. 2) In the course of economic development, regional environment situation in China has continuously been changing, and there exists the difference of environmental quality between provinces, which is bigger than that of economic development level between there. 3) Except veryfew provinces, regional EPI in China has risen in varying degrees since the 1980s, which shows that the task for China toprevent environment from polluting is still arduous.
