Arrays NgFor仅支持绑定到Iterables（如数组），同时使用数组创建下拉选择

我在运行应用程序时遇到以下错误：

错误：找不到类型为“subLandscape”的不同支持对象“[object object]”。NgFor仅支持绑定到阵列之类的iTerable。

我在HTML中提到的subLandscape变量是一个数组，但它在与“ngFor”一起使用时抛出一个错误

HTML:

组成部分：

import { Component, OnInit } from '@angular/core';
import { Standalone } from '../standalone';
import { StandaloneModel } from '../models/standalone.model';
import {MatTableModule, MatTableDataSource} from '@angular/material/table';

@Component({
  selector: 'app-standalone-form',
  templateUrl: './standalone-form.component.html',
  styleUrls: ['./standalone-form.component.css']
})
export class StandaloneFormComponent {
  public project: string[] = ['', 'appdev', 'apptest', 'appqa'];
public subLandscape: string[] = ['DEV', 'Testing', 'QA', 'UAT'];
  public dataCenter: string[] = ['PDC', 'SDC'];
public model = new SModel('', '', '', '', '', 0, '', '');

}

可能是因为它无法区分

subLandscape

和

---

#subLandscape=“ngModel”

和组件属性数组

公共subLandscape:string[]=['DEV'，'Testing'，'QA'，'UAT']。更改其中一个的名称应该可以解决问题，可能是因为它无法区分
子Landscape

export class SModel {
