矿产资源开发会造成一定程度的水土流失。例如露天开采形成采空区,导致地面

矿产资源开发会造成一定程度的水土流失。例如露天开采形成采空区,导致地面沉降和塌陷。矿产资源开发也会砍伐树木、占用土地,并且对土壤造成污染,使土质遭到破坏。这些都可能导致矿区附近的水土流失加剧。本文中矿产资源开发对水土流失的影响分析主要是分析矿区水土流失与矿区所采土壤中Cu、和Zn等金属元素含量的关系。通过前文第4章根据遗传神经网络算法得到的2009年那研究区水土流失分级结果,统计每个水土流失级别区域土壤中Cu、和Zn等金属元素丰度和均值,结果见图7。由图8可见水土流失程度较低的区域土壤中金属元素的丰度值较高。均值相对也较高。反之水土流失越严重的区域土壤中金属元素含量越低。从而说明土壤中的金属元素含量会随着水土流失而稀释﹐矿产资源开发对水土流失较弱区域的影响要大于强度水土流失地区。缓冲区半径的选取如过大则缓冲形成的水质响应单元大部落在矿区范围外,同时考虑到用于本次土地利用信息提取的TM数据分辨率为30m,半径太小提取出的地类信息不能真实反映地表实际情况。根据前人研究经验结果,结合研究区实际情况,通过实验最终选取1500m作为河流水质断面监测点的缓冲半径。以采样点为中心,建立半径为1500m的缓冲区,再分析缓冲区内地化元素的分布情况。如图9所示微观尺度的研究以矿区水系上游和下游的小流域和缓冲区为研究单元,统计每个区域内污染元素含量的平均值和丰度等数据结果,以此为依据讨论矿产资源开发对小流域和缓冲区产生的影响,并进行对比。然后分析小流域和缓冲区内部采样点水系、土壤和水系沉积物中的相关金属元素含量随某江流向自上游到下游的空间变化情况。并进一步分析矿产资源开发对土地覆被类型、植被覆盖度、生物多样性等因子的影响。如图10所示缓冲区和小流域尺度的分析说明了化学元素含量的两个丰度指数和平均值为基础来进行研究。利用区域统计功能对整个流域水系沉积物中Cu元素含量值的插值结果进行统计,得到每个小流域和缓冲区内含量值的最大值、最小值、标准差和均值等,并计算出两个丰度指数,其中一个为CaCb,另一个丰度指数为Cm/Cb。具体结果见表8所示。

The development of mineral resources will cause a certain degree of soil erosion. For example, open-pit mining forms a goaf, which leads to ground subsidence and subsidence. The development of mineral resources will also cut down trees, occupy land, and pollute the soil, causing soil quality to be destroyed. These may lead to increased soil erosion near the mining area. <br>The analysis of the impact of mineral resources development on soil erosion in this article is mainly to analyze the relationship between soil erosion in mining areas and the content of Cu, Zn and other metal elements in the soil collected in the mining area. Based on the results of the 2009 soil erosion classification in the study area obtained in Chapter 4 according to the genetic neural network algorithm, the abundance and average value of Cu, Zn and other metal elements in the soil of each soil erosion level area are calculated, and the results are shown in Figure 7. <br>It can be seen from Figure 8 that the abundance of metal elements in the soil is higher in the areas with lower soil erosion. The average is relatively high. Conversely, the more serious the soil erosion, the lower the content of metal elements in the soil. This shows that the content of metal elements in the soil will be diluted with soil erosion, and the impact of mineral resource development on areas with weak soil erosion is greater than that of areas with intense soil erosion. <br>If the buffer radius is too large, the water quality response unit formed by the buffer will be outside the mining area. At the same time, considering that the resolution of the TM data used for this land use information extraction is 30m, the radius is too small to extract the land type information Can not truly reflect the actual situation on the surface. Based on the results of previous studies and the actual situation of the study area, 1500m is finally selected as the buffer radius of the monitoring point of the river water quality section through the experiment. Taking the sampling point as the center, establish a buffer zone with a radius of 1500m, and then analyze the distribution of geochemical elements in the buffer zone. The <br>micro-scale research shown in Figure 9 takes the small watersheds and buffer zones upstream and downstream of the mining area as the research unit, and counts the average and abundance of pollutant elements in each area, and discusses mineral resources based on this. Develop and compare the impact of development on small watersheds and buffer zones. Then analyze the spatial variation of the relevant metal element content in the water system, soil and water system sediments of the sampling points in the small watershed and buffer zone from upstream to downstream with the flow of a certain river. And further analyze the impact of mineral resources development on land cover types, vegetation coverage, biodiversity and other factors. As shown in Figure 10<br>The analysis of the buffer zone and the small watershed scale shows that the two abundance indexes and the average value of the chemical element content are used as the basis for the research. Use the regional statistics function to calculate the interpolation results of the Cu element content in the sediments of the entire watershed, and obtain the maximum, minimum, standard deviation and mean value of the content in each small watershed and buffer zone, and calculate two Abundance index, one of which is CaCb, the other abundance index is Cm/Cb. The specific results are shown in Table 8.

The exploitation of mineral resources will cause a certain degree of soil erosion. For example, open-pit mining forms a mining area, resulting in ground subsidence and collapse. The exploitation of mineral resources can also cut down trees, occupy land, and pollute the soil, causing damage to the soil. All of this can lead to increased soil erosion near the mine.<br>In this paper, the impact of mineral resources development on soil erosion is mainly analyzed in the mining area soil erosion and mining areas in the soil of Cu, and Zn and other metal elements content. Based on the results of soil erosion classification in the study area in 2009 based on the genetic neural network algorithm in Chapter 4 above, the abundance and mean of metal elements such as Cu and Zn in each soil loss level area are counted, as shown in Figure 7.<br>It can be seen from Figure 8 that the abundance value of metal elements in soil in areas with low soil erosion is high. The mean is also relatively high. On the contrary, the more serious soil erosion, the lower the metal content in the soil. Thus, the content of metal elements in soil will be diluted with soil erosion, and the impact of mineral resources development on the weaker areas of soil erosion is greater than that of intensity soil erosion.<br>The selection of buffer radius such as too large buffer formed water quality response units are mostly outside the mining area, taking into account that the TM data used for this land use information extraction resolution of 30m, the radius is too small to extract the earth-type information can not truly reflect the actual situation on the surface. According to the results of previous research experience, combined with the actual situation of the study area, 1500m was finally selected as the buffer radius of the river water quality section monitoring point. With the sampling point as the center, a buffer with a radius of 1500m is established, and the distribution of the inland elements of the buffer is analyzed. As shown in Figure 9<br>The microscale study takes the small basins and buffer zones upstream and downstream of the water system in the mining area as the research unit, and counts the average and abundance data results of the pollution element content in each region, so as to discuss the impact of mineral resources development on small basins and buffer zones and compare them. The content of related metal elements in water system, soil and water sediments at sampling points in small basins and buffer zones is then analyzed with the spatial changes of a river flowing from upstream to downstream. The influence of mineral resources development on land cover type, vegetation cover and biodiversity is further analyzed. As shown in Figure 10<br>The analysis of buffer and small basin scales shows that the two abundance indices and averages of chemical element content are used for research. Using the regional statistics function, the interpolation results of Cu element content values in water system sediments in the whole basin were calculated, the maximum, minimum, standard deviation and mean values of content values in each small basin and buffer were obtained, and two abundance indices were calculated, one for CaCb and the other for Cm/Cb. The results are shown in Table 8.

Then, the spatial variation of metal element contents in water system, soil and stream sediment of sampling points in small watershed and buffer zone from upstream to downstream was analyzed. Furthermore, the effects of mineral resources development on land cover type, vegetation coverage and biodiversity were analyzed. As shown in Figure 10<br>Buffer zone and small watershed scale analysis showed that the content of chemical elements was based on two abundance indices and average values. By using the regional statistical function, the interpolation results of Cu content in stream sediments of the whole watershed were statistically analyzed, and the maximum, minimum, standard deviation and mean value of Cu content in each small watershed and buffer zone were obtained, and two abundance indices were calculated, one was CACB, the other was cm / CB. The specific results are shown in Table 8.<br>
