Wind farms have obvious impact on the local climate. However, whether there exist obvious differences in environmental effects of local wind between the inland and offshore wind farms still need to be explored. Based on the inland wind farm data from Shangyi, Hebei Province and offshore wind farms in Rudong, Jiangsu Province and the data of meteorological observation and wind gradient tower around wind farm the influence difference of the inland and offshore wind farms on local wind environment, turbulence intensity (TI) and wind shear exponent (WSE) are preliminarily analyzed. The results show that the inland and offshore wind farms have significant effects on TI and WSE. The constructed inland and offshore wind farms have an enhancement effect on TI, and the average annual TI increased by 31% and 37%, respectively. The largest increment occurred in spring (47%) and winter (49%) in inland and offshore wind farms respectively. Moreover, the TI increasing range of high-level was greater than that in low-level, and greater at night than in day in inland wind, while the TI increasing range was relatively stable at different heights and diurnal variation in offshore wind farms. In terms of WSE, the constructed inland and offshore wind farms have significant differences in their influences on WSE. The WSE increased during the day and decreased at night, and the diurnal variation was significantly reduced with the average annual WSE decreased by 8%, and the largest decline in WSE in autumn (12%) in the inland wind farms. By contrast, the WSE increased obviously during both day and night with average annual WSE increased by 24%, and the largest rise seen in spring (37%) in offshore wind farms.
