Reduction of quality and soil productivity due to organic carbon losses is one of the most important consequences of land use changes, that creates irreparable effects on the soil. To evaluate the land use effect on the amount of soil organic carbon in Vertisols, Sartip Abad series with extent of 1850 hectare in south of Bilehvar area in Kermanshah province was studied by using the completely r...

River restoration projects are often accompanied by major land consolidation operations, notably the re-allocation of adjacent farmland, which offers opportunity to create an extensively-managed buffer zone outside levees where specific habitat features installed for endangered terrestrial and semi-aquatic biodiversity. Modern, enrivonmentally-friendly operations might thus not only contribute ...

We introduce the Gini coefficient to assess the rationality of land use structure. The rapid transformation of land use in China provides a typical case for land use structure analysis. In this study, a land Gini coefficient (LGC) analysis tool was developed. The land use structure rationality was analyzed and evaluated based on statistical data for China between 1996 and 2008. The results show...

As the basic unit of farmland, parcel is crucial for remote sensing tasks, such as urban management. Previous studies farmland parcels extraction are based on boundary detection and instance segmentation methods. However, these methods perform poorly in with complex shape fuzzy due to insufficient feature capability. Moreover, lack multi-scale features fusion, they difficult extract different s...

The Heihe River Basin (HRB) is a typical arid inland river basin in northwestern China. From the 1960s to the 1990s, the downstream flow in the HRB declined as a result of large, artificial changes in the distribution of water and land and a lack of effective water resource management. Consequently, the ecosystems of the lower reaches of the basin substantially deteriorated. To restore these de...
