摘      要：Crop straw is an important natural resource in China because it is rich in *** returned to fields after harvests,the straw can improve soil quality and the next crop’s *** the economic values of the main ecological services of a farmland ecosystem while implementing the straw return technique can be a more systematic and comprehensive approach to better understand the contribution of straw return to the development of ecological *** on the data of a field experiment established in 2010 with varying numbers of years of straw return,four ecological services,i.e.,agricultural product and industrial raw materials,atmospheric regulation and purification,soil nutrient accumulation,and water conservation,were selected to estimate a net ecosystem service value(ESV)of a wheat field’s ecosystem ***-ecosystem service appraisal theories were applied to estimate the economic value of each *** showed that straw returning improved the total ESV in the wheat *** to the no straw return treatment,1 year,3 years,5 years or 7 years of straw returning altered the economic value of the agricultural product and industrial raw materials(EVAIM)by-5.93%to 7.84%and improved atmospheric regulation(EVAR)by 13.66%-30.80%,soil nutrient accumulation(EVSNA)by 59.87%-233.31%and water conservation(EVWC)by 2.60%-13.26%.The total ESV of wheat plots with 1-7 years of straw returning was 3.67%-27.41%higher than that with no straw return,and the total ESV increased with the increase in years of straw *** proportion of EVAIM out of the total ESV in this wheat field system was highest(accounted for 47.09%-55.64%),followed by EVAR and *** value of EVSNA was the ***,the proportion of EVSNA was higher than that of water conservation after the fifth year of straw *** general,the adoption of continuous straw returning in a wheat field ecosystem is ecologically *** results can inform the development and i
