青州市南张楼村土地质量地球化学特征及特色土地资源评价

Geochemical Characteristic of Land Quality and Typical Land Resources Evaluation in Nanzhanglou Village in Qingzhou City

摘要:

本文以青州市南张楼村为研究区，基于村级土地质量地球化学调查数据，开展土壤养分、土壤环境、土壤质量及特色土地资源评价。结果显示，土壤养分N以较缺乏、中等为主；P以丰富为主；K以中等、较丰富为主；土壤养分地球化学综合等级以较丰富为主，土壤养分总体水平较好。土壤环境单指标Zn存在小面积的污染风险，污染等级为风险可控，其他指标均为无风险，土壤环境地球化学综合等级以无风险为主，土壤环境清洁。土壤质量地球化学综合等级以一等（优质）和二等（良好）为主，土壤质量优良。本次研究共发现耕地富硒土壤0.08km2、富锗土壤0.93km2，富锌土壤3.61km2，表明研究区特色土地资源丰富。

Abstract:

Taking Nanzhanglou village in Qingzhou city as the research area, based on geochemical surveying data of land quality under village level, evaluations of soil nutrients, soil environment, soil quality and characteristic land resources have been carried out. It is showed that the soil nutrient N is mainly deficient and medium. P is rich, K is mainly medium and rich, comprehensive grade of soil nutrient geochemistry is rich, and the overall level of soil nutrients is better. As a single indicator of soil environment, Zn has a small area of pollution risk, and the pollution level is controllable. The comprehensive grade of soil environmental geochemistry is risk-free, and the soil environment is clean. The comprehensive geochemical grade of soil quality is mainly first class (high quality) and second class (good), and the soil quality is excellent. In this study, it is found that selenium rich soil is 0.08km2, germanium rich soil is 0.93km2, and zinc rich soil is 3.61km2. It is indicated that typical land resources are rich in the study area.
