Application of importance-performance analysis (IPA) has received wide applicability to reveal resident’s satisfaction with the performance of ecological services. In recent days, researchers have expanded the horizon of IPA through the implication of this technique in case of different ecosystem services to find out the satisfaction of local people with ecosystem services. However, a little contribution has been made in the field of wetland study through IPA. This study has tried to apply IPA in this field by taking into consideration of 10 common ecosystem services. The study unit is Chatra Wetland, which is a peri-urban wetland of the English Bazar city. Analysis of LULC of the past 18 years suggests that the net area of Chatra Wetland got reduced by >50 percent during this time. Besides this, decreasing the value of LPI, PLAND, cohesion, and CONTAG represents the fragmentation of the landscape of Chatra Wetland. The predicted LULC shows that this wetland will disappear by 2040 if the LULC conversion rate remains the same. In this regard, IPA is performed to understand the satisfaction level of the citizen of English Bazar city and the people of surrounding villages with the performance of Chatra Wetland. The output of IPA reveals that people are dissatisfied with the performance of five ecosystem services. These are biodiversity, flood control, water supply, identity, and cooling effect. All of them require the urgent need of attention to restoring the ecological condition in the study area. Overall, the performance rate of Chatra Wetland at present is perceived by the urban people as only 55.14 percent. However, the rate of perceived performance varies ward-wise and village-wise. It is observed that place attachment and proximity to Wetland have made a vital role in the perception of people. The perceived performance of Chatra Wetland is increasing gradually with increasing distance from the Chatra Wetland. The output of this study helps to reveal the importance of this wetland to the urban people as well as to the local villagers by identifying their satisfaction level and their enjoyment with the urban blue space. It also serves as a basis of the bottom-up approach of environmental management to the decision-makers by displaying the demand of people in case of ecological restoration.

重要绩效分析（IPA）的应用已得到广泛应用，以显示居民对生态服务绩效的满意度。近年来，研究人员通过在不同生态系统服务的情况下使用该技术来扩展IPA的范围，以发现当地人对生态系统服务的满意度。但是，通过IPA在湿地研究领域做出了一些贡献。通过考虑10种常见的生态系统服务，本研究试图将IPA应用于该领域。该研究单位是Chatra湿地，这是一个围-英国巴扎尔市的城市湿地。对过去18年的LULC的分析表明，这段时间内查特拉湿地的净面积减少了50％以上。除此之外，降低LPI，PLAND，凝聚力和CONTAG的值表示Chatra湿地景观的碎片化。预测的LULC表明，如果LULC转化率保持不变，到2040年该湿地将消失。在这方面，执行IPA是为了了解Chatra Wetland的表现，以了解英国巴扎尔市公民和周围村庄居民的满意度。IPA的输出表明，人们对五种生态系统服务的绩效不满意。它们是生物多样性，防洪，供水，特性和降温效果。所有这些都迫切需要关注，以恢复研究区域的生态状况。总体而言，城市居民目前认为查特拉湿地的性能水平仅为55.14％。但是，感知绩效的比率在各个区域和各个村庄都不同。据观察，地点依附和与湿地的接近在人们的感知中起着至关重要的作用。随着距离Chatra Wetland距离的增加，Chatra Wetland的感知性能逐渐提高。这项研究的结果有助于确定湿地对城市居民和当地村民的重要性，方法是确定他们的满意度和对城市蓝色空间的享受。
