The WTP study was conducted among 345 waters users in 19 barangays in the municipalities of Solano and Bayombong. Uncensored data revealed that 63.8% (58.84% for the adjusted) of the respondents revealed willingness to pay for improved watershed management. The mean WTP amount, estimated through a logit model, Turnbull Distributor-Free Estimator and Lower Bound Estimate, is found to be PhP39.35, PhP27.80 and PhP25.90/month/household, respectively. Respondents WTP is influenced by bid amount, age, membership in environmental organization, experience with water-related problems, civil status, house ownership, and awareness on the concept of watershed. Respondents were willing to pay because they wanted a sustainable water supply for the present and future generations. A payment scheme is possible and it could provide a sustainable flow of fund, however, the willingness percentages still needed to be increased. Community education and public awareness (CEPA) campaign is necessary to enhance the water users’ knowledge and understand about the importance and values of watersheds. Ultimately, WTP percentage and WTP amounts would increase.展开更多

In order to improve the reliability of CV, WTP and WTA is used syn-chronously to estimate the restoration cost of Maqu grassland ecosystem. Data were partly from questionnaire survey, and partly from interviews and authorities. Before conclusions were derived, we assumed these data that came from interviews and authorities were right. The main result is: If we assumed that the degraded grassland of Maqu needs 10 years to be restored, and divided the restoring period into two stages, then the restoration cost was 0.85 × 108 RMB per year in former 4 years, 0.022 × 108 RMB per year in latter 6 years. The total cost of Maqu grassland restoration was 3.62 × 108 RMB. For all the costs of restoration, WTA occupied 94% and WTP only occupied 6%, suggesting that local grassland degradation was mainly caused by overgrazing and that the overloading livestock must be eliminated in order to achieve restoration successfully. Our research also showed that combining WTP and WTA in contingent valuation is very useful in estimating the cost of environmental improvement projects. Of course, whether these results are right or not, further researches are needed in the future, especially for the actual number of livestock in Maqu grassland.展开更多

Law and ethics play the most outstanding role in it. Family ethics and moral standards constitute an important part of social ethical system while marriage and family constitute part of the legal system nearest to the life of the common people. Since the founding of New China, the Party and the State have paid full attention to the marriage and family system. Compared with other laws, the law about marriage and family was the first to be legislated. On May 1, 1950, New China’s first law, the 1950 version of Marriage Law, was promulgated.
