Xinjiang County Limestone Stone Mine Land Reclamation Engineering Measures And Cost Benefit Analysis

In this paper, taking the land reclamation project of Zhangjiazhuang Stone Plant in Xinjang County of Shanxi Province as an example, this paper explores the present situation of land use in the project area from the perspective of exploratory and researching, and obtains the information of the land- The land reclamation project in the project area is analyzed and evaluated based on the actual objective conditions of the project area, and then the cost and benefit of the reclamation project are analyzed and evaluated. Analyzed. The results show that:(1) According to the results of land damage analysis and prediction, the area of reclaimed land is expected to be 2.79hm~2, including the final platform, step platform and step slope after restoration. The reclaimed land is 1.79hm~2, shrub land 0.45hm~2, artificial grassland 0.55m~2, land reclamation rate of 100%. (2) After planting the platform, the platform is reclaimed to cultivated land; the platform is reclaimed into forest land. In order to prevent soil erosion and landslide, only thin cover soil is used in the slope, and the mountain slope is prepared with acacia, and the sowing is also done by sowing the other parts of the plant. Alfalfa. (3) The total dynamic investment of the project is 1.0731 million yuan, the static total investment is 321,600 yuan; the reclaimed land area is 2.79hm~2, the dynamic investment per unit area is 384,600 yuan/hm~2,25643 yuan/mu; Static investment of 11.53 yuan/hm~2, together 7684 yuan/mu. (4) After the implementation of the project to bring significant benefits, the project can be reclaimed into dry land 1.79hm~2, shrubland 0.45hm~2, artificial pastures 0.55hm~2. Effectively curb the deterioration of the study area and the surrounding environment, and finally achieve the diversity and stability of plant ecosystem on the basis of rational management and protection.
