Abandonment of agricultural land is a global issue and a waste of resources and brings a negative impact on the local economy. It is also one of the key contributing factors in certain environmental problems, such as soil erosion and carbon sequestration. In order to address such problems related to land abandonment, their spatial distribution must first be precisely identified. Hence, this stu...

The anaerobic oxidation of ammonium (anammox) process has been observed in diverse terrestrial ecosystems, while the contribution of anammox to N2 production in paddy soils is not well documented. In this study, the anammox activity and the abundance and diversity of anammox bacteria were investigated to assess the anammox potential of 12 typical paddy soils collected in southern China. Anammox...

one of the crucial issues before the second cropping is having enough knowledge about the residue effect of first crop herbicides on second crops. this experiment was conducted to investigate the possible inhibitory effect of some selective paddy herbicides residues to second cropping. experimental factors were included common paddy herbicides (thiobencarb, butachlor, oxadiargyl, bensulfuronmet...

With the popularization of network and the development of information technology, as a new mode of marketing, network marketing has been accepted by the majority of consumers, and applied rapidly to the field of clothing marketing. This paper describes the present situation of China clothing industry network marketing at first. Then it points out the advantages and disadvantages of network mark...

Paddy soils distribute widely from temperate to tropical regions, and are characterized by intensive nitrogen fertilization practices in China. Mounting evidence has confirmed the functional importance of ammonia-oxidizing archaea (AOA) and bacteria (AOB) in soil nitrification, but little is known about their biogeographic distribution patterns in paddy ecosystems. Here, we used barcoded pyrose...

Recent field studies in rice paddy fields in Japan and China have shown that N2O is emitted to the atmosphere not only after the application of nitrogen fertilisers under flooded conditions but also in a period from the final drainage to submergence in the following rice-growing season through nitrification or denitrification. Those results clearly indicate that CH4 and N2O emissions in rice pa...

This study aimed at the development of method of monitoring paddy rice planting applicable to areas located in the tropical humid climate region. The method was integrated with two steps of procedure. As the first step, we attempted to produce land use map which discriminated paddy field using multi-temporal Landsat data. In order to remove the effect of cloud cover, a new method of land use cl...

[1] Large-scale assessments of the potential for food production and its impact on biogeochemical cycling require the best possible information on the distribution of cropland. This information can come from ground-based agricultural census data sets and/ or spaceborne remote sensing products, both with strengths and weaknesses. Official cropland statistics for China contain much information on...

A Web-based hybrid intelligent system, WebIntegrated (developed by the authors), for developing blended e-marketing, mobile marketing and social media marketing strategies is reported in this paper. The concepts, software system and associated elements or components are presented. A brief demonstration of the data entries and outputs are also provided.

Research on change in land use and landscape pattern is the foundation for studies exploring natural and cultural landscape of a region. This study used GIS software and utilized topographic maps to examine the changes that occurred in the Oguraike floodplain, during the time points of 1888, 1909, 1961, and 2002. The Oguraike floodplain, which was dominated by the landscape of Oguraike Pond and...
