摘要
基于土地生态健康评价原理,选取化学需氧量和氨氮指标对用于灌溉的地表河流进行评价,为区域土地利用提供依据。以河南省台前县为例,通过对研究区内地表河流金堤河(黄河北侧支流)进行为期1 a的动态监测(2011年1月1日至12月19日),通过水样实验分析,得到污染物指标实验数值,以此为依据计算土地健康综合指数,并给予合理评价。对影响土地健康的灌溉水因子的综合分析表明,研究区土地灌溉水质量综合指数居中等以上,土地健康状态较为良好,土地灌溉水综合指数较为合理,反映了土地利用、经济布局与资源环境压力状况,从而为区域可持续发展提供理论基础。
The purpose of this research is to evaluate surface irragation waters based on the principle of land ecological health assessment, chemical oxygen damand and Ammonia nitrogen indicator, which provide references for regional land use. The case study of this research selects Taiqian County in Henan Province. By dynamically monitoring the surface water in the research area, Jindi river(branch in the northen Yellow river) for a year(from Jenuary 1st,2011 to December 19 th,2011) and analyzing water samples, we can get pollutant indicator data, which calculate the land health aggregative index and evaluate accordingly in a proper way. By analyzing irrigation water indicators that affect land health, it comes to the conclusion that the aggregative index of land irragation water quality in the research area is larger than mediate, which indicates that the land health condition is better. The aggregative index of land irragation water quality in the research area is reasonable. It reflects land use, economic layout, pressure on resource and environment and it can provide a theoretical basis for regional sustainable development.
