摘要

尼泊尔中部山区的农民采用多种耕作制度。该地区的城郊地区人口密度较高，在农业方面面临着一些问题。虽然丘陵因易侵蚀而遭受侵蚀，但城郊地区面临要素生产率下降的问题，特别是在集约耕作的农田。本研究的重点是在土壤管理实践的基础上模拟区域范围内的农业收入。空间显式模拟表明，由于退化造成的农业收入损失在丘陵地区要大得多，而在山谷底部则要小得多。空间环境中的战略制定和测试表明，地理信息系统是模拟特定干预措施后果的适当方法工具。关键词:中山，尼泊尔，空间建模，土壤质量指数，农业收入DOI: http://dx.doi.org/10.3126/hjs.v6i8.3243喜马拉雅科学杂志Vol.6 Issue 8 2010 pp.27-34

Simulating farm income under the current soil management regime in the mid-hills of Nepal

Farmers in the mid-hills of Nepal follow diverse farming systems. The peri-urban area of this region, where population density is higher, faces several problems in farming. While hills suffer from erosion because they are erodible, the peri-urban areas face the problem of decline in factor productivity, particularly in intensively cultivated farmlands. The present study is concerned with simulating farm income on a regional scale based on soil management practices. Spatial explicit simulation shows that the loss of farm income due to degradation is substantially higher in hills while it is lower in valley bottoms. Strategy formulation and testing in the spatial environment indicates that Geographic Information System is an appropriate methodological tool for simulating the consequences of particular interventions. Key words: Mid hills, Nepal, spatial modeling, soil quality index, farm income DOI: http://dx.doi.org/10.3126/hjs.v6i8.3243 Himalayan Journal of Sciences Vol.6 Issue 8 2010 pp.27-34

期刊介绍： The "Journal of Himalayan Earth Sciences" (JHES) is a biannual journal, managed by the National Centre of Excellence in Geology, University of Peshawar, Pakistan. JHES is recognized by Higher Education Commission (HEC), Pakistan in "X" Category. The JHES entertains research articles relevant to the field of geosciences. Typical geoscience-related topics include sedimentary geology, igneous, and metamorphic geology and geochemistry, geographical information system/remote sensing related to natural hazards, and geo-environmental issues and earth quake seismology, and engineering and exploration geophysics. However, as the journal name implies, the articles addressing research relevant to the above disciplines in the Himalayan region will be given prime importance and relevance.
