Research Progress of Regional Soil Water Resources Evaluation
摘要
Abstract
Being as a part of water resources,the research significance and application value of soil water have been paid more attention pro-gressively,but the study about assess the soil water still shows insufficient. Soil water content can be obtained through direct calculation or indirect inversion,but as an important part of hydrologic cycle,soil water is linked with regional national economy. Hydrologic budget should be regarded as the foundation of evaluation methodology,using indexes like the circulation volume and refresh water resource to characterize the quantity of resource,and the influence on soil water from natural recharge and manual irrigation should be distinguished. Some tools like Distributed Hydrological Model and remote sensing had been utilized,coupled soil water movement model to achieve the scale transformation, and combined with the quantity evaluation of soil water resources to acquire the distribution of soil water resources under different spatial and temporal scales.关键词
