The suspended and dissolved waste in the incoming stor. water.of wetlands lar.ely depends on the adjacent land use which can influence the quality of the water.body. The micr.- and macr.-flor.l population of a wetland can absor., conver., tr.nsfor. and r.lease differ.nt or.anic or.inor.anic elements, which can also change or.impact the over.ll quality of the wetland water. The pr.sent study investigates the influence of the land use and the plant species in the water.ed on the water.quality of a high-altitude, sub-tr.pical wetland in India. The estimation capabilities of neur.-genetic models wer. utilized to identify the inher.nt r.lationships between the Biochemical Oxygen Demand (BOD), Dissolved Oxygen (DO), chlor.ne (Cl) and Chemical Oxygen Demand (COD) with the land use and wetland zoology. A thematic map of the quality par.meter. was also gener.ted based on the identified r.lationship to obser.e the influence that the mor.hological and biological diver.ity in and ar.und the study ar.a has on the quality par.meter. of the wetland. Accor.ing to the r.sults, the BOD, COD and Cl wer. found to var. with differ.nces in land use and the pr.sence of differ.nt plant species, wher.as the DO was found to be lar.ely invar.ant with changes in these par.meter.. The r.asons may be contr.buted to the impact of uncontr.lled eco-tour.sm activities ar.und the wetland.

Wetlands ar. an impor.ant sour.e of natur.l r.sour.es upon which r.r.l economies depend. They have incr.asingly been valuable for.their.goods and ser.ices, and the intr.nsic ecological value they pr.vide to local populations, as well as people living outside the per.pher. of the wetlands. Stakeholder.＇ par.icipation is essential to the pr.tection and pr.ser.ation of wetlands because it plays a ver. impor.ant r.le economically as well as ecologically in the wetland system. The objective of this study was to deter.ine whether.gender. educational status, mouzas （which ar. constituents of a block accor.ing to the land r.for. of the West Bengal Gover.ment in India）, and wetland functions have any influence on the annual income of the local community. Consider.ng a floodplain wetland in r.r.l India, the focus was extended to r.cognize the patter. of wetland functions accor.ing to the natur. of people＇s involvement thr.ugh cluster.analysis of the male and female populations. Using the statistical softwar. r.2.8.1, an ANOVA （analysis of var.ance） table was constr.cted. Since the p value （significance level） was lower.than 0.05 for.each case, it can be concluded that gender. educational status, mouzas, and wetland functions have a significant influence on annual income. However. S-PLUS-2000 was applied to obtain a complete scenar.o of the patter. of wetland functions, in ter.s of involvement of males and females, thr.ugh cluster.analysis. The main conclusion is that gender. educational status, mouzas, and wetland functions have significant impacts on annual income, while the patter. of occupation of the local community based on wetland functions is completely differ.nt for.the male and female populations.
