土地质量地球化学调查成果应用于永久基本农田划分方法技术
|
摘要
为了探讨土地质量地球化学调查取得的地球化学指标与土地环境指标应用于基本农田土地质量评价的思路与流程,通过基本农田概念与功能、基本农田划定的需求、土地质量指标与地球化学调查成果的关联性等分析,提出充实基本农田数据库、农产品安全指标与品质指标、土壤肥力指标、生态环境指标等应用于基本农田划分及后备基本农田选区评价的方法、思路与工作流程。研究结果表明,土地质量地球化学调查各项成果指标及图件应纳入到基本农田图、表、册中,土地质量环境指标评价中对超过土壤污染管制值的土壤实行一票否决,调出基本农田;对满足无公害产地要求的富硒集中连片区等,应直接纳入基本农田中;对其他指标可根据不同的功能区要求,纳入到综合评价中。永久基本农田评价需进一步吸收利用地质学、地球化学等方面的成果资料,从影响耕地的物理、化学、生态、地理等方面进行全面科学的评价,体现土地资源的本质属性。
This paper aims to explore the process of thinking and procedure of applying geochemical indicators and land environmental indicators obtained from geochemical investigation of land quality to evaluating land quality of basic farmland and guaranteeing the realization of the aim that the land quality of basic farmland meet the demands of quantity as well as quality, safety and other requirements of agricultural products. Based on analyses of the concept and function of basic farmland, its delimitation, the relevance of land quality indicators with geochemical survey results, and some other aspects, the authors put forward methods, ideas and work processes for enriching the database of basic farmland and applying such indexes as safety and quality index of agricultural products, soil fertility index and ecological environmental index in the division of basic farmland and the evaluation of basic farmland reserve districts. Indexes and maps resulting from the land quality geochemical research should be incorporated into the maps, tables and lists of basic farmland; land of super class Ⅲ standard soil shouldn't be considered as basic farmland; rich selenium concentrated area with no pollution should be directly incorporated into the list of basic farmland; other indicators could be included into comprehensive evaluation according to the requirements of different functional areas. Researchers should further absorb geological,geochemical and other data to make a comprehensive scientific evaluation of physical, chemical, ecological and geographical aspects that affect cultivated land, so as to reflect the essential attributes of land resources.
