Guyuan City County Forestry And Ecological Construction Planning Function Evaluation

The Ningxia Guyuan original state area is situated at middle and upper reaches west Yellow River's Loess Highlands, once reclaimed wasteland in the history by the big area, the extensive cultivation to maintain in the livelihood the insufficient part, finally causes the soil erosion more to cultivate seriously is poorer.The western big development strategy for two years, Returning farmland to forest, the wildwood resources conservation project and so on key forestry ecological building project primarily starts comprehensively in the original state area, has completed the ecology forestry construction project to afforest 445,000 Chinese acres, closes off hillsides to facilitate afforestation 130,000 Chinese acres.The forestry ecological building project's ecology, the social efficiency initially obviously the result, has been approved by the original state area broad masses, proved that the forestry ecological building project the implementation is very essential, has the profound significance to ecological environment's construction and the economical sustainable development.The paper research take the Guyuan original state area's forestry construction and the benefit as an object, in elaborated the research development and refers to the massive material in the foundation, has conducted the investigation and study on the original state area forestry construction plan's in key technologies question and the anticipated benefit appraisal, its main conclusion is as follows:1. the basis dissimilar condition, the original state area may use the Liupanshan periphery conifer and broadleaf to mix hands over the forest for water conservation pattern, northeastern part the arid piece including water to guarantee the protective forest pattern, the ecology economy concurrently with the forest pattern, Lin Cao to unify the pattern and the forest medicine interplanting pattern 5 planters is disposed the pattern.2. acts according to the original state area natural environment characteristic, may divide is three type areas, namely half cloudy wet soil lithical mountainous area, half arid loess hill gully area, arid loess rolling country.3. the pair of original state area afforestation design is 26 types, and according to vertical floristic component Lin Zhong method naming, has been clear about the protection type to the protective forest.Proposed the ecology economy disposition pattern, the ecotype pattern and the highly effective economic forest pattern 3 kind of more typical disposition pattern plan. 4. proposed the Liupanshan periphery forest for water conservation constructs the model district, the Qingshui river basin protective forest to construct the model district, the arid loess rolling country fuel forest to construct the model district, the Qingshui river basin ecology economy protective forest to construct the model district 4 essential demonstrativeness construction area.5. the preliminary study thought: After forestry project implementation, the self-control water source's economic efficiency is 243,540,000 Yuan, maintains the water and soil total benefit is 17,880,000 Yuan, the small basin government performance for may reduce above Sha Jianliu 90_, the timber production benefit is 576,000,000 Yuan, the agriculture additionally receives 136,500,000 Yuan, the agriculture puts into production the ratio is 1:4.1.Improves the original state area ecological environment the forestry project comprehensive implementation, simultaneously is advantageous to the entire district economic structure adjustment and the social economy full scale development, for countryside advance in technology and social productive forces further development creation good condition.And thought that this region the forestry benefit related indicator system determined in detail, still waited for further deep research.
