Land Subsidence is a kind of slow evolution geological hazards which needs effective way to monitor. The causal and developmentsof land subsidence are complex. The monitor of land subsidence is also difficulty. So it is hard to analyze it in independent data source. This paper uses multiple source data to extract the high temporal and spatial resolution result. The deformations of land surface ...

road network (rn) can affect patterns and distribution of land uses and covers. road network expansion has both direct and indirect impacts on land uses and covers changes. agricultural land conversions (alcs) are especially known as one of the main important types of land use changes. the purpose of this paper, in addition to estimation of the direct impact of rn expansion on alcs, is to evalu...

soil condition to those characteristics suitable (fit) for a particular land use. Also implicit in this brief definition Information on soil conditions in New Zealand is needed to assess is the capacity for the soil to maintain its fitness into soil quality at a national scale. We tested a standard set of 16 primary indicators at 29 sites (0–10 cm depth) across nine soil great groups the future...

Despite numerous previous studies, relationships between watershed land use and adjacent streams and rivers at various scales in Korea remain unclear. This study investigated the relationships between land uses and the physical, chemical, and biological characteristics of 720 sites of streams and rivers across the country. The land uses at two spatial scales, including a 1-km buffer and the bas...

Drought index is a useful tool to assess and respond to drought. However, current drought indices could not fully reveal land use effects and they have limitations in applications. Besides, El Niño Southern Oscillation (ENSO), strongly influences the climate of Florida. Hence, understanding ENSO patterns on a regional scale and developing a new land use drought index suitable for Florida are cr...

This project analyzes the impact of land titling on child health and education. The empirical evaluation of the effect of land property rights typically suffers from selection problems. The allocation of property rights across households is usually not random but based on wealth, family characteristics, political clientelism, or other mechanisms built on differences between the groups that acqu...

Tropical forests of the Amazon Basin are being rapidly converted to agricultural land uses and fallow land, resulting in accelerating rates of forest loss in one of the world's most biodiverse ecoregions. This process has been extensively described and modelled, but as yet there has been no formal test of how the spatial patterns of deforested and fragmented areas change with the spatial scale ...

soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure.so, this research has been done for achieving this purpose. this area is arounding sa...

heavy metals in high concentrations in soils are potential health risk for humans, animals, and plants. soil samples were collected in five replicates from 20 points with four land use including: roads, refineries, residential area (sadra town), and farmland. heavy metals were determined using flame atomic absorption (analyticjena), while dtpa was chosen as trace elements extractor. in this stu...
