  Introduction: This research has studied to determinate the value of preservation of Shirkooh zone andadjacent outdoor recreation villages and measured the individuals willingness to pay (WTP) forpreservation profits of this zone.Material and Method: Logit model was used for measuring of individual's willingness to pay andestimation parameters of the model are based on method of maximum likely hood (ML).Result and Discussion: The results showed that 79.1% individuals have the willingness to pay forpreservation of this zone. In this study, the mean of WTP for preservation value of this zone is31250 Ir. Rials per month per household. Therefore Shirkooh promenade zone has considerablepreservation value and this value, policy and decision persuades the suitable preservation of this zone. Manuscript profile

  Renewable natural resources have had a fundamental role in economic and social development of societies during history. Increasing environmental disasters has also concerned economists as well as environmental specialists, and has made the experts at management level to realise the need for protection and sustainable use of natural resources. In this study, it was tried to determine the economical value of Urmia Lake,usingLogit method which is based on people’s willingness to pay, by CVM method and WTP measurements. The main purpose of this study was to provide non-consumable value (conservation value) of this lake. In this method, 31 variables were investigated. The estimation of the model was carried out using the Logit method with EVIEWS software (10). Analyzing the results indicated that the amount of willingness to pay for each unit price rise is decreased by 21%. Finally, the average value of WTP for non-consumable economic value of UrmiaLake was estimated to be 52.58x103 and the total economic value of the lake was estimated to be $605 million.

  Bamdej Wetland is located 40 km north of Ahwaz, with area of 4000 hectares. Bamdej Wetland is a natural wetland with great ecological, scientific outing and economical value which in case it can be preserved and revived will raise all values as a self regulating collection.First, the ranges of studies were identified ,and four sampling stations were selected. The were sampled randomly. During experiments BOD5, COD, nitrates, phosphates, pH, electrical conductivity, turbidity, temperature, DO, salinity, TSS and TDS were measured. Then, the results of water quality system are exmind. Ecological evaluation study area was performed using fusion rapid assessment and TOPSIS. In this way resources were based to 13 groups include: the extent of the wetland, vegetation around the wetland, the width of buffer, soil status, connecting with other water sources, depth of wetland, source of water supply, time of wetness, normal disturbances, habitat development, type of wetland cover, and biodiversity of plants. Comparing the annual quality indicator of each station with a table of water quality index indicate that the station 3 is belong to the third group and station 1, 2 and 4, belong to fourth group classification system of water quality indicator. Finally, Bamdej Wetland earned 59 points of 85 possible points of rapid evaluation method. This expression that wetland desirable conservation value is (grade 2). TOPSIS method was used for analys some important ecological factors of Bamdej Wetland. The results confirm that wetness time of Bamdej Wetlands weighing of 1.483 is the most important criteria of its value.   Manuscript profile
