Chaoyang County full-benefit analysis of small watershed

Date value according to a formula 3.44 million, effective area of 57.3 hectares. Increase the output value of 1.971 million yuan jujube. h: Apricot. Five years of implementation of the area of 224.79 hectares, save l97.64 hectares, an area of 108.86 hectares effective governance end, apricot increase output per hectare calculated by the formula of 300 yuan, 32,700 yuan output value of governance to increase the end, the end of 2005 according to a formula increase of output value l3.98 million. Final Economic Analysis 2.1.2 per hectare ① governance: 3299600/1369 = 2366 yuan. Final output per hectare ② Governance: 1264000/1369 = 923 yuan. ③ net benefit: l26.4-329.96 =- l97.56 million. ④ benefit cost ratio: l26.4/329.96 = 0.38. ⑤ 2005 at the end of output per hectare is: 42l3500/1369 = 3078 yuan. ⑥ benefit cost ratio: 422.62/329.96 = 1.28. The calculation and analysis, governance, end of period net benefit is negative,[link widoczny dla zalogowanych], the benefit cost ratio is low, there are two main reasons: First, treatment is difficult, more investment and work; Second, some measures have not yet entered into force. After nearly 8 years of training, management, increase the value of the end of 2008 reached 4.2262 million yuan. 2.2 Benefits of Soil and Water Conservation Benefits of Soil and Water Conservation 2.1.1 Calculation (1) storage capacity calculations. Grammar before the water treatment basin for many years to calculate the average runoff for the l86.27 million m; water protection laws to calculate the watershed from 1993 to 1997 the annual volume of water management measures for the lO9.69 million m, and calculate the before the original terrace watershed management,[link widoczny dla zalogowanych], village forest water storage capacity of the existing 212,800 m, therefore, at least five years after treatment of small watershed total annual water l3O. 970 000 m3. (2) water efficiency calculation. Small basin full of average runoff for the l86.27 million m, total water storage after treatment l3O. 970 122, the storage efficiency of 70.3%. (3) water-effectiveness calculations. Construction of water storage basin unit of the local cost of 0.4 yuan / m. The water efficiency B = l30.97X0.4: 52.39 million. (4) Calculation of Soil Conservation. Drainage area of 17.74km, the basin erosion modulus 2818.4t / a · km. Formula used by the five-year watershed management and soil conservation measures in the annual volume of 34,800 t, and calculate the control before the original terraces, villages and forest land and soil conservation capacity of 05,800 t, the actual basin soil conservation capacity of 40,600 t. (5) and soil conservation efficiency calculation. Years before the watershed average soil erosion amount of 50,000 t, the year after treatment and soil conservation amounted to 40,600 t, the soil conservation efficiency of 81.2%. (6) Calculation of soil conservation benefits. Local river dredging, construction of embankments of the earthwork cost 5 yuan / m. 40,600 t 31,200 divided by the coefficient of 1.3 m, the soil conservation benefits for the 3.12 × 5 = l5.6 million. 2.1.2 water, and soil conservation benefits of full of small watershed management through the years, storing runoff governance by the former 212 800 m, increased to l30.97 million m, a treatment of runoff m down in front of l86.27 million to the current 553,000 m, effective water governance by the former 8.50 million yuan to 524,000 yuan storing sediment governance by the former 05,800 t, increasing to 40,600 t, the amount of erosion control in front of 50,[link widoczny dla zalogowanych],000 by the t, down to the present 09,400 t, and soil conservation benefits from current 2.2 million yuan to 15.6 million, of which agricultural terraces storing sediment 0.9l million t, and soil conservation benefits of 3.5 million. 2.3 The full ecological and social benefits of watershed rule after 5 years of comprehensive management, the forest cover rate has increased from 3.9% to 53.8%. After five years of treatment, 8 years after treatment, with the local cadres and the masses continue to repair and careful management and protection, terrace soil gradually ripening, fruit trees, old growth, production increased year by year, effectively attract and stimulate local agriculture, forestry , animal husbandry, processing,[link widoczny dla zalogowanych], transportation and other industries. By the end of the year, calculated over the initial two villages within the catchment of the total output value has reached 9.566 million yuan, 2,702 yuan per capita GDP, the total income of 6,692,000 yuan, the per capita net income of 1,891.6 yuan.
