中文摘要： 近年来松嫩平原盐渍土壤面积不断扩大，土壤质量退化日趋加剧，不但对该区域的土地资源造成了巨大的破坏，而且对农业生产和生态环境构成巨大的威胁，因此，及时、准确、动态地获取盐渍化土壤的遥感信息，对治理盐渍土、防止其进一步退化和进行农业可持续发展至关重要。本项目旨在把遥感的偏振信息、多角度信息和高光谱信息有机地结合起来，通过对松嫩平原盐渍化土壤多源光谱特征信息的获取，建立普适的模型，研究盐渍化土壤对光谱信息的响应机理与方法，突破了传统研究中仅仅利用单一光谱信息研究和表达土壤信息单一化的局限性，科学使用正交试验设计的方法，充分利用土壤的多源光谱特征数据，有效地体现了这些因素间交互作用的影响。可以说这是一项颇具前瞻性的研究与填补空白性质的研究。此项研究成果，为松嫩平原盐渍土光谱研究提供一个新的途径，为遥感技术识别、分析土壤及参数提供科学依据，对区域生态、经济可持续发展具有重要意义。

英文摘要： In recent years, the area of saline soil in Songnen Plain expands increasingly, and soil quality is becoming more and more worsening, which not only caused great damage to the land resources, but also posed a huge threat to agricultural production and ecological environment. So it is very important to obtain the timely, accurate and dynamic remote sensing information for managing saline soil, preventing further deterioration and the sustainable development of agriculture. This project aims to combine with polarized, multi-angle and hyperspectral information to establish the general model. We could get the multi-source spectral information from saline soil in Songnen Plain, which break through the traditional research using single spectrum and one-sidedness of soil information. Then we design a scientific orthogonal experiment and interaction analysis, making full use of multi-source data and seeking the influence factors from them. Therefore, it is to be a more forward-looking study. This study could provide a new way for the research on the saline soil spectra and analyze soil salinization and parameters in Songnen Plain, which is of great significance to the sustainable development of regional ecological and economic.
