سابقه و هدف: پايداري زيستمحيطي بيان‌كننده‌ي اقدامات مادي و غيرمادي است كه اطلاعاتي كليدي از آثار محيطزيست، رعايت مقررات، روابط ذي‌نفعان و دستگاه‌هاي سازماني فراهم مي‌آورد و نشان‌دهنده‌ي تعاريفي از اثربخشي و بهره‌وري اقدامات صورت گرفته در محيطزيست است. عملكرد زيستمحيطي به معني ميزان تأثيراتي است كه فعاليت فيزيكي انسان بر روي محيطزيست مي‌گذارد. اين شاخص بر ابعاد پايداري محيطزيست تأكيد داشته و عملكرد سياست‌ها و برنامه‌هاي كشورها را درزمينه ي كاهش معضلات محيط زيستي و حفاظت از محيطزيست و مديريت منابع طبيعي موردسنجش و ارزيابي قرار مي‌دهد. هدف كلي اين تحقيق، تحليل اثرات عملكرد زيست محيطي روستائيان بر ادراك آنها نسبت به پايداري زيست محيطي در شهرستان باغملك بود .
مواد و روش ها: تحقيق حاضر داراي ماهيت كمي است كه ازنظر هدف جزو تحقيقات كاربردي و ازنظر نحوه گردآوري و پردازش داده‌ها جزو تحقيقات توصيفي ـ همبستگي به شمار مي‌رود. جامعه آماري تحقيق شامل سرپرستان خانوار روستاهاي بخش مركزي شهرستان باغملك بودند (N=3005). حجم نمونه با استفاده از جدول كرجسي و مورگان 341 نفر محاسبه‌شد (N=341)و افراد نمونه با استفاده از روش نمونه‌گيري تصادفي طبقه‌اي تناسبي موردمطالعه قرار گرفتند. ابزار گردآوري داده‌ها در اين تحقيق، پرسشنامه بود . روايي ظاهري و محتوايي پرسشنامه با نظـر كارشناسـان و متخصصـان درزمينه ي موضوع موردپژوهش مورد تأييـد قـرار گرفـت . بـراي تعيين پايايي ابزار تحقيق، مطالعـه راهنمـا انجام گرفت كه مقـدار آلفـاي كرونبـاخ براي مقياس‌هاي اصلي پرسشنامه در حد مطلوب (0.78 تا 0.91) بدست آمد.
نتايج و بحث: نتايج آمار توصيفي نشان داد ميانگين ادراك پاسخگويان نسبت به پايداري زيست محيطي (3.66 از 6) بدست آمد. همچنين ميانگين عملكرد زيستمحيطي (3.79 از 6) محاسبه شد. از بين مولفه هاي عملكرد زيست محيطي، مولفه مصرف با ميانگين (4.36 از 6) و مولفه بازيافت با ميانگين (3.45 از 6) به ترتيب بالاترين و پايين ترين اولويت را به خود اختصاص دادند. نتايج مدلسازي معادلات ساختاري نشان داد مقادير پايايي تركيبي (CR) و ميانگين واريانس استخراج شده (AVE) محاسبه شده مؤلفههاي عملكرد زيست محيطي در سطح مطلوبي بدست آمد. با توجه به وجود همبستگي معنيدار بين مولفه هاي عملكرد زيست محيطي اين سازه از روايي منطقي برخوردار بود.نتايج بدست آمده از ضرايب اندازه گيري نشانگرهاي متغير ادراك پاسخگويان نسبت به وضعيت پايداري زيست محيطي نشان داد مقدار شاخص ميانگين واريانس استخراج شده در حد مناسب و مقدار پايايي تركيبي در سطح مطلوب بدست آمد. همچنين وجود همبستگي معنيدار بين نشانگرها نشان داد اين متغير از روايي منطقي قابل قبولي دارا ميباشد. نتايج مدلهاي ساختاري نشان داد عملكرد زيستمحيطي تاثير مثبت و معني داري بر ادراك پاسخگويان نسبت به پايداري زيست محيطي داشت. به طوري كه اين متغير 13 درصد از تغييرات ادراك را تبيين نمود. همچنين نتايج بدست آمده نشان داد مولفههاي سه گانه عملكرد زيستمحيطي (مصرف، نهادي و بازيافت) تاثير مثبت و معنيداري بر ادراك پاسخگويان نسبت به پايداري زيست محيطي داشت. به طوري كه اين مولفه ها 24 درصد از تغييرات ادراك را تبيين كردند.
نتيجه گيري: به عنوان يك نتيجه كلي مي‌توان بيان داشت در روستاهاي مورد مطالعه ، لازمه‌ي انجام رفتار محيط زيستي، داشتن اطلاعات كافي در مورد عملكرد محيط زيستي مي باشد. درنتيجه هر چه مهارت روستاييان به سطوح بالاتر عملكرد مثبت زيستمحيطي سوق پيدا كند رفتارهاي سازگارتر با محيطزيست از خود بروز خواهند داد كه اين رفتارها ميتوانند به ارتقاي پايداري زيست محيطي كمك نمايند.

Introduction:
Environmental sustainability represents material and non-material actions that provide key information on environmental impacts, compliance, stakeholder relationships, and organizational systems and represent definitions of the effectiveness and productivity of environmental actions. Environmental performance means the amount of impact that physical activity has on the environment . It highlights the environmental sustainability dimensions and assesses the performance of policies and programs of countries in reducing environmental problems, environmental protection and natural resource management. The purpose of this research was to analysis the effects of villagers environmental performance on their perception toward environmental sustainability in Baghmalek county.
Material and methods:
The present study is quantitative in terms of its nature and objectives, a descriptive survey in terms of data collection, and a correlation study in terms of analyzing the data. Statistical population of the study was rural households heads in central region of Baghmalek township located at Khuzestan Province (N=3005). Sample size determined via Krejcie and Morgan’s table (n=341). Sampling method was proportional stratified random sampling. Research instrument was questionnaire. Which its face and content validity were confirmed a by panel of experts. To determine the reliability of the research tool, a pilot test was conducted that the Cronbach's alpha values for the main scales of the questionnaire was in the desirable range (0.78 to 0.91).
Results and discussion:
The results of descriptive statistics showed that the mean of respondents' perception toward environmental sustainability was 3.66 out of 6. Also, the calculated mean for environmental performance was 3.79 out of 6. Among the components of environmental performance, consumption with average (4.36 out of 6) and recycling with average (3.45 out of 6) had the highest and lowest priority, respectively. The results of structural equation modeling showed that the values of composite reliability (CR) and extracted mean variance (AVE) calculated for environmental performance components were obtained at optimum level. Considering the significant correlation between environmental performance components, this structure had logical validity. The results of the measuring coefficients of the items of respondents' perception toward environmental sustainability showed that the value of the AVE was at the appropriate level and the CR was at the optimum level. Also, there was significant correlations between items of perception showed that this variable had acceptable logical validity. The findings of structural equation modeling (SEM) showed that environmental performance had positive and significant effect on the respondents perception toward environmental sustainability. So that this variable explained 13 percent of the variance in perception. Also, results showed that three components of environmental performance (consumption, institutional and recycling) had positive and significant effect on the respondents perception toward environmental sustainability. So that these components could explain 24 percent of the of the variance in respondents perception.Conclusion: As a general conclusion, it can be said that in the villages under study, environmental behavior needs to be adequately informed about environmental performance. As a result, as villagers' skills lead to higher levels of positive environmental performance, will perform more environmentally friendly behaviors that can help promote environmental sustainabilityMaterials and Methods: The present study is quantitative in terms of its nature and objectives, a descriptive survey in terms of data collection, and a correlation study in terms of analyzing the data.Statistical population of the study was rural households heads in central region of Baghmalek township located at Khuzestan Province (N=3005).

So that this variable explained 13 percent of the variance in perception. Also, results showed that three components of environmental performance (consumption, institutional and recycling) had positive and significant effect on the resopndents perception toward environmental sustainability. So that these components could explain 24 percent of the of the variance in respondents perception.
Conclusion:
As a general conclusion, it can be said that in the villages under study, environmental behavior needs to be adequately informed about environmental performance. As a result, as villagers' skills lead to higher levels of positive environmental performance, will perform more environmentally friendly behaviors that can help promote environmental sustainability
