吉林省西部葵花种植区地球化学环境评价

为利于吉林西部葵花产区种植结构调整和区域农业发展规划,根据种植区土壤类型、地质背景等因素,选择农安巴吉垒、大安龙沼和通榆新安作为研究区,在分析盐碱化土地利用过程中的土壤生态地球化学特征的基础上,运用模糊综合评判法对吉林省西部葵花种植区的地球化学环境进行综合评价.结果表明,通榆工作区各类土壤农业生态地球化学环境质量均属于一级;大安工作区草甸风砂土、盐化黑钙土、石灰性草甸土属一级,而淡黑钙土和草甸碱土属三级;农安工作区草甸黑钙土和草甸碱土属二级,石灰性黑钙土、盐化草甸土和石灰性草甸土属三级.研究区总体农业生态地球化学环境质量不佳,需要加大生态补偿与恢复.

Geochemistry Environment Assessment of Sunflower Growing Areas in the West of Jilin Province

For the planting structure adjustment and regional agricultural development planning of sunflower planting area in the west of Jilin Pronvince,according to factors of planting area soil types,and geological background,Bajilei of Nong＇ an and Longzhao of Da＇ an and Xinan of Tongyu was selected as the research area,based on the analysis of soil ecological geochemistry feature in the used process of land saline-alkalized,fuzzy comprehensive evaluation method was used to evaluate the geochemistry environment of sunflower growing areas in the west of Jilin Province.The results showed that,various agro-ecological geochemistry of soil environmental quality in Tongyu is class 1,Meadow Wind Sand and Salt Chernozem and Calcareous meadow soil in Da＇ an are class 1,and others are class 3,in Nong＇ an,Meadow Chernozem and Meadow alkali soil are class 2,and others are class 3.The results indicated that agro-ecological geochemistry environmental of the research area is not good,and it needs ecological compensation and recovery.
