Abstract: The number and distribution of road garbage bins have an important relationship with the urban appearance construction, and also have an important significance for improving the utilization rate of resources. This paper investigates the types and distribution of trash bins on both sides of the road in the built-up area of Chuxiong City, and uses the average center, median center, center elements, and direction distribution methods to evaluate the distribution of trash bins. The results showed that the sanitation trash bins on both sides of the main road are less distributed, there are not enough garbage bins on both sides of the eastern fringe road, the overall number and direction of trash bins are unevenly distributed, the number of garbage transfer boxes and sanitation garbage bins is small and they are unevenly distributed. According to the existing problems, this paper made the following suggestions: three types of trash bins should be set in areas where residents live, the number of garbage bins should refer to the density of residents, garbage transfer box and sanitation garbage box should be placed according to the standard, the trash bins should be set in a prominent position.

$\stackrel{¯}{X}\text{=}\frac{\underset{i=1}{\overset{n}{\sum }}Xi}{n},\text{\hspace{0.17em}}\text{\hspace{0.17em}}\stackrel{¯}{Y}=\frac{\underset{i=1}{\overset{n}{\sum }}Yi}{n}$

$\text{\hspace{0.17em}}{d}_{i}^{t}=\sqrt{{\left({X}_{i}-{X}^{t}\right)}^{2}+{\left({Y}_{i}-{Y}^{t}\right)}^{2}}$

$SD{E}_{x}=\sqrt{\frac{\underset{i=1}{\overset{n}{\sum }}{\left({x}_{i}-\stackrel{¯}{X}\right)}^{2}}{n}}$

$SD{E}_{y}=\sqrt{\frac{\underset{i=1}{\overset{n}{\sum }}{\left({y}_{i}-\stackrel{¯}{Y}\right)}^{2}}{n}}$

$\mathrm{tan}\theta =\frac{A+B}{C}$

$A=\left(\underset{i=1}{\overset{n}{\sum }}{\stackrel{˜}{x}}_{i}^{2}-\underset{i=1}{\overset{n}{\sum }}{\stackrel{˜}{y}}_{i}^{2}\right)$

${\sigma }_{x}=\sqrt{2}\sqrt{\frac{\underset{i=1}{\overset{n}{\sum }}{\left({\stackrel{˜}{x}}_{i}\mathrm{cos}\theta -\stackrel{˜}{y}\mathrm{sin}\theta \right)}^{2}}{n}}$

${\sigma }_{y}=\sqrt{2}\sqrt{\frac{\underset{i=1}{\overset{n}{\sum }}{\left({\stackrel{˜}{x}}_{i}\mathrm{sin}\theta +{\stackrel{˜}{y}}_{i}\mathrm{cos}\theta \right)}^{2}}{n}}$

4. 研究结果

Figure 1. Three kinds of garbage can

1) A类垃圾桶分布情况

A类垃圾桶总体数量较少，空间分布稀疏，多是沿街分布，楚雄市建成区西南和西北方向因商铺小区分布较为密集，A类垃圾桶错落分布在其中间，但楚雄市建成区中部区域分布数量较少且分布密度低(图2)。

Figure 2. Distribution of class A garbage cans

2) B类垃圾桶分布情况

B类垃圾桶总体数量不多，多数是以一定间隔沿道路分布在两侧，小区及商业街内部分布较少，但总体位置分布较全面，但数量不足(图3)。

3) C类垃圾桶分布情况

C类垃圾桶沿道路两侧分布，数量众多，空间分布密度大，多数C类垃圾桶分布在道路两侧，小区内部数量较少(图4)。
